Theme songs are extremely crucial in the wrestling industry. We have seen some names go from mid-carder to stardom through a simple change of their music, which was the case for Stone Cold Steve Austin. As great as his character turned out to be over the years, he wouldn't have had the same impact without the iconic glass shatter and the music that followed. And while theme songs are used in other industries such as boxing, they don't have nearly as much important as it does in wrestling.

Fans come to associate their favorite stars with a theme song, as it usually serves to represent their character. They are also crucial to get a reaction from the crowd - whether positive or negative - and that is the reason why so many faces change their music once they turn heel and vice versa.

Throughout the years, we have seen many names become relevant mainly due to their theme song, as we recently witnessed with Bobby Roode's Glorious. Despite his impressive career outside of the WWE, his new character is now based on his entrance rather than years of past work. But as helpful as theme songs can be, they could also damage a wrestler's career and such has been the case for many names.

Some are lucky to immediately find the perfect music to come out to, while others get stuck with a terrible entrance that holds them back in many ways. Here are 15 theme songs that seriously hurt a wrestler's career:

15 William Regal

William Regal is considered to be one of the most underrated Superstars in WWE history. And what may have held him back is that terrible first theme song of his, known as a "Real Man's Man." The song is so bad that it's good and has become a meme among wrestling fans. A few years ago, the backstage officials played it in the middle of his entrance as a prank to Regal which got a laugh from him and members of the audience who still remembered the theme song.

Regal did go on to have a decent career, especially in his late years, but he was always at a disadvantage from the start due to this cringeworthy theme that he never truly recovered from. His second theme wasn't much better, and it took a third try for WWE to find him a suitable one which he went on to use for the rest of his career.

14 Rob Conway

Rob Conway was part of La Resistance for two years and won the World Tag Team Championship three times. In 2005, the team split up and Conway adapted a new persona as well as theme song. He started to really resemble Buff Bagwell from his look down to his mannerisms. But it was the theme song that made him memorable for all the wrong reasons as it's a strong contender for the worst of all time.

Despite a mini push from the company, Conway failed as a singles competitor and didn't last long in the WWE. You can only go so far with that terrible theme song, so it's no surprise that he became a laughing stock. As for Conway, we are willing to bet that he pretends as if that run never happened and looks more fondly on his days with La Resistance alongside Sylvain Grenier.

13 Lance Storm

Despite being an impressive wrestler, Lance Storm never truly found a lane in the WWE. He was always praised for his in-ring ability while criticized for being relatively boring compared to fellow Superstars. His lack of charisma held him back from going to the next level, which ultimately became his character as Storm adapted a more fun persona in which he danced his way to the ring.

The theme "Party Away" is quite possibly the worst fitting one for any wrestler, and removed whatever credibility Storm had left. It is now remembered for all the wrong reasons since it did more damage to Storm's career than anything else. WWE's constant attempts to give him a personality fell flat, and he probably would have been better off sticking to his WCW character. Storm never recovered following his stint with "Party Away" and only lasted a few months afterwards before being released from the WWE.

12 Chavo Guerrero

The problem with Chavo Guerrero is that he has always been overshadowed by his uncle Eddie. The latter is one of the most complete all-around performers in wrestling history, which is a tough task for anyboy to compete with. Chavo isn't exactly bland but his charisma leaves plenty to be desired when compared to Eddie.

But Chavo is talented enough to have had a two decade career in which he worked for the top wrestling promotions. He hasn't been taken very seriously since 2005 - at least in the WWE - when he switched characters to Kerwin White, which brought along one of the worst theme songs in wrestling history. He switched back to Chavo once Eddie passed away, but fans never forgot his stint as Kerwin White - a gimmick that no wrestler could have gotten over due to how silly it is. If you missed out on Chavo's brief run as Kerwin, the titantron will provide you with the laugh of the day.

11 Cesaro

A few years ago, fans were still talking about Cesaro being a main eventer. As days went by, that dream became more unrealistic with everyone now accepting that he will remain a mid-carder. Although he was never given a major push, Cesaro always had the support of the fans. Vince McMahon once said that Cesaro was lacking "it", adding that he has failed to connected with the audience.

It is nearly impossible to do so when you have the worst theme song on the current roster - a major downgrade from his previous "Miracle" entrance. It's hard to really react to those annoying sirens, and one of the many reasons why Cesaro hasn't been able to advance to the next level. A new theme song is much needed for Cesaro get his career back on track now that his tag team run with Sheamus has run its course.

10 Christian

From 2004 to 2005, Christian had arguably his best run in his WWE career. Although he didn't achieve major success, he was on fire at the time and became among the top heels. Christian had a great theme song, nickname and outfits to match. He also reached new levels on the mic, which really established a fanbase. After leaving the WWE for three years, Christian returned to the ECW brand in 2009.

That run proved to be more successful but it happened at a time when the WWE roster was at its worst. Christian was no longer as charismatic as his peeps had known him, and his run was stale for the most part. He had always been a much better heel than face, but that came too late in his most recent run. Another factor was his awful new theme song, which was a remix of his older one.

9 Brie Bella

Nikki and Brie Bella look like identical twins so an argument that the former being more successful due to her looks cannot be made. Although you can say that she has an advantage in some areas, including a certain enhancement that we can't forget. But while Nikki has a memorable theme song and a beloved entrance, Brie lacks in both departments.

It is probably the very same reason why Brie never matched her level of success, although Nikki having the support of John Cena may have also played a part. It's safe to say that Brie may have achieved more if she wasn't stuck with one of the worst theme songs in recent history. But she probably doesn't lose too much sleep considering the success she has had within the company and with her reality show, considering how little talent she has to offer.

8 Marcus Cor Von

Marcus Cor Von, previously known as Monty Brown, was one of the best talents in TNA. He fell short of holding the NWA Championship, yet managed to become one of the most popular wrestlers outside of the WWE. Upon making the switch to WWE, he was doomed to fail from the start with a name like Marcus Cor Von. Having him on the struggling ECW brand didn't help matters either, but it was his theme song that sealed his fate.

For someone who was supposed to be charismatic yet so powerful, he had a goofy theme song that damaged his credibility from his debut. Cor Von wrestled for WWE for a year before asking to be released in order to attend personal matters. He had the whole package from charisma to mic skills, as well as a brilliant finisher, yet he never really connected with the WWE Universe. Not so smooth after all.

7 Brodus Clay

Brodus Clay is another Superstar who was set to fail from the day he made his roster debut. It seems like WWE was confused about booking him, and didn't know whether they wanted Clay to be a monster or a comedy act. He ended up being a failed character at a relatively short time, and his theme song didn't do him any favors. He did have some fans towards the start but interest quickly faded away once they realized that Brodus would be stuck in the very same position for the rest of his career.

History indicates that similar gimmicks never work, regardless of how hard Vince McMahon attempts to push them. Brodus Clay was prime example and is now remembered for all the wrong reasons. But at least he did earn some hefty paychecks to dance around in the ring for some years.

6 T.L. Hopper

In the 90s, WWE witnessed a trend of workers turned wrestlers - most of whom flopped and became a joke shortly afterwards. Among them was T.L. Hopper, who portrayed a plumber, and came out to one of the most ridiculous theme songs of all time. It was just a toilet flushing, which I guess was used to emphasized that he is a plumber.

It's hard to believe that a creative team came up with that idea and agreed on releasing it to the public, which goes to show where WWE was headed prior to the Monday Night Wars. T.L Hopper only lasted a year in the company and never worked for any major company afterwards, so it's safe to claim that his theme song foreshadowed his wrestling career. Not only does he have a strong case for the worst theme song of all time, but the same could be said about his character.

5 The Hurricane/Gregory Helms

Fans may forget that The Hurricane had a run as Gregory Helms, which was relatively successful although not exactly memorable. The persona was bland to say the least, and he failed to connect with the audience the way his previous gimmick did. He has stuck with The Hurricane since then and even made a surprise appearance at the 2018 Royal Rumble with his old gimmick. As for Gregory Helms, he had a very generic look and a theme song that sounds like it belongs to a jobber.

Despite the company's best attempts to push Helms, he never recaptured the magic of the old days and he may have been better off sticking to The Hurricane for his entire career. Although his more serious persona may have worked if he had been given a different look and theme song, but both ended up being horrendous in many ways.

4 X-Pac

The X-Factor theme is a guilty pleasure song for many people although they may not be willing to admit it. During the peak of X-Pac heat, his theme song changed to what has become known as the X-Factor song, since X-Pac as well as his stable used it. There are so many things wrong with the song from the random intro to the lame lyrics, and not to mention that it didn't fit X-Pac at all.

Not an ideal theme for a wrestling entrance either, and all these factors combine to create one of the worst theme songs known to mankind. X-Pac's career was already struggling during that era, and theme change made sure he never recovered again as he spent his final days in the low-card before being released from the company. If X-Pac didn't have any heat prior to the song, then he certainly did once it changed.

3 Big Show

Big Show was once the strongest force in the wrestling industry and it's easy to see why. Despite having had a long and successful career, most agree that booking failed him for the most part as he should have been much closer to Andre The Giant in status. One of the many reasons that made sure Big Show would never reach his full potential is the change of his theme song upon his move to ECW, which stuck with him to this day.

It's a slowed down remix of his original theme, which was much more intimidating and fitting for the giant, as opposed to the newer version. But of course that's only one of the many factors that held back Big Show, he was involved in some terrible storylines over the years. And like every monster WWE has ever had, they went the comedy route with Big Show as well.

2 The Great Khali

The Great Khali has never been a great wrestler, nor has he ever connected with the fans. But he did have major success in his first two years with the company, feuding with the likes of The Undertaker, Batista and John Cena. He even captured the World Heavyweight Championship along the way, yet WWE gave up on Khali and turned him into a comedy act for the latter part of his career.

With a new gimmick came a new theme song, which was terrible in so many ways. If the silly character wasn't enough to hurt his status, that new theme song surely did the job. Khali would remain on the roster much longer than he should have before WWE finally came to its senses and let him go. Khali hasn't been taken seriously since his theme song changed, and he will probably be remembered for the latter part of his career rather than the early days.

1 Right To Censor

Right To Censor was a short lived faction that consisted of some of WWE's most controversial characters, which was created as a response to complains from Parental Television Council (PTC). WWE was being criticized for the raunchy and violent content with many demanding for the company to be taken off television, which prompted a response from Vince McMahon. The concept for the group was an interesting one, but they never really reached their potential as a faction.

The annoying theme song played a part, and while that may have been the entire purpose of the entrance, we still think that it could have been much better. To their credit, they did gain some heat towards their early run, but like so many other WWE projects, the company eventually gave up on the group and they got less interesting by the day, which meant that fans stopped caring after a while.
