One of the most important aspects of the professional wrestling industry's ability to make a star is their entrance, as it's each individual's literal introduction to the audience to establish who they are, what their character is about and whether they should be cheered or booed.
While it wasn't always this way, as the business only adopted music regularly in the 1980s, it has now become so instrumental -- pardon the pun -- that the entrance themes are truly iconic.
However, what is strange is when you look back in history and see that someone's theme was actually used earlier, before trying it out for themselves.
It feels wrong, almost like someone pressed the wrong button on the sound board and the production team made a mistake, or if someone were tweaking things in a WWE 2K game to purposely go against the grain.
New Champs in WWE! More RIGHT HERE
Still, there are plenty of examples of Superstars adopting someone else's theme as their own and making it so synonymous with their characters that we forget anybody else even used it.
Here are just ten examples of times where a particular theme was used by more than one WWE Superstar.
#1 "Medal" by Jim Johnston
If you ask most fans about theme songs used by another person, this is likely to be the first one they bring up.
Kurt Angle has used "Medal" for the entirety of his career in WWE, but it wasn't written specifically for him at all.
Instead, this was a generic patriotic theme to the point where it had been used in several different ways ahead of time when tied to someone with a similar gimmick.
For example, Sgt. Slaughter temporarily used this song, but it was even more famously used by Del Wilkes while he wrestled under the masked gimmick of The Patriot.
#2 "This Fire Burns" by Killswitch Engage
Before CM Punk was able to adopt Living Colour's "Cult of Personality" into his WWE career, his theme was "This Fire Burns" by Killswitch Engage.
He used this theme for years in ECW, leading up to the point where his storyline revolved around being frustrated with the company.
This was a hand-me-down from Randy Orton of all people, who had used it briefly in 2006 before transitioning to "Burn in my Light" and then his current, and many would say the best theme, "Voices."
#3 "Somebody Call My Momma" by Jim Johnston
No song on this list has been passed around as much as "Somebody Call My Momma", which first was attributed to Ernest "The Cat" Miller and was showcased tremendously in the 2004 Royal Rumble, wherein he and his manager Lamont danced in the ring.
They were promptly eliminated by Christ Benoit and Randy Orton, and soon enough, the song would fade into the background archives.
It saw a massive resurgence several years later, though, when Brodus Clay was reintroduced in confusing fashion, not as a monster heel, but a dancing guy smiling from ear to ear.
Clay formed a posse with Tensai (later known as Sweet T) and The Funkadactyls (Cameron and Naomi) who all utilised the song for their entrances.
Oddly enough, The Funkasaurus actually lost the ability to use the theme anymore directly in a feud with newcomer Xavier Woods, who then adopted it as his own for a short period of time.
It hasn't been resurrected since Woods used it last, but here's hoping it comes back in the future.
#4 "Insatiable" by Patsy Grime
Not every song can be a hit and sometimes not every song can even make sense to be a good fit in a wrestling capacity at all.
"Insatiable" by Patsy Grime is one of those cases where it seems completely out of place as a wrestler's theme if you pay attention to the lyrics.
The melody and tempo are fine, but when your entrance starts off with "I'm insatiable, I can't get enough. I need to find a boy" and you're just trying to illustrate that you are an athlete and a fighter, it's just ridiculous.
This was a different era, though, as it was used first by ECW general manager Tiffany (better known as Taryn Terrell) before it was passed over to Layla after she split from Michelle McCool and needed something of her own for the remainder of her in-ring career in the company.
In neither capacity did it make any sense, as one woman was supposed to be an authoritative role and the other one was a wrestler, while neither of them were portraying characters who were boy-crazy.
Nowadays, in the current climate of the women's wrestling revolution, there's no way this would fly for any wrestler who was meant to be taken seriously.
#5 "Not Enough for Me" by Jim Johnston
Prior to becoming insatiable, Layla was one of many women who came out to Jim Johnston's rather generic, but useful "Not Enough for Me" theme.
This was originally meant for Torrie Wilson, but the woman who truly made it her own was Michelle McCool, who used it for the majority of her career.
When McCool partnered up with Layla to form LayCool, this was the theme that they kept for the duo since McCool was clearly the more dominant personality of the two and Layla's theme at the time wasn't going to turn any heads.
#6 "Pa-Pa-Pa-Pa-Party" by Jim Johnston
Mike and Maria Kanellis now come out to the new love ballad "True Love" by CFO$, but one of Maria's old themes actually stuck around long enough that it's still being used today.
Not many will remember Maria using "Pa-Pa-Pa-Pa-Party" (or for that matter, what song that necessarily is just by the title of it) but it is actually Alicia Fox's current theme which she's been using for pretty much her whole career.
Even years ago, let alone now, hearing this energetic tune has to evoke memories of Fox spinning something above her head and acting all crazy rather than anything related to Maria.
#7 "With Legs Like That" by Zebrahead
Maria's most tenured theme is definitely "With Legs Like That" by Zebrahead, but if you listen to the lyrics and you know the history of the song, you can understand that it wasn't written for her at all.
While certainly no slouch in the looks department and undoubtedly incredibly attractive in many, many ways, it's doubtful a song with that title and lyrics like "Her legs go on and on for days" is going to be the product of a brainstorm session about Maria.
Instead, it was actually Stacy Keibler's theme beforehand, which makes much more sense, considering how her legs were her most iconic feature.
#8 "Dragon" by Jim Johnston
Convenient naming could play a big factor in why multiple people have used "Dragon" by Jim Johnston.
This was used for Ultimo Dragon before it became tied to Ricky "The Dragon" Steamboat, who has used it ever since, using it as his own many years back.
Since Steamboat has a much stronger tie to WWE than Ultimo Dragon, this has stuck with the WWE Hall of Famer much more and whenever we're treated with an appearance from the legend, as soon as the opening notes sound, the crowd knows exactly which of the two to expect.
#9 "Never Thought My Life Could Be This Good" by Jim Johnston
Ready for a weird one? Of course you are.
The Frank Sinatra style of "Never Thought My Life Could Be This Good" was originally used for Chavo Guerrero's Kerwin White character with lyrics specifically pointing to this, talking about gated communities, private schools, soccer moms and such.
Eventually, this was gifted to Michael Cole of all people!
His ridiculous heel character faded away over time and he started to use a more generic, upbeat production theme called "Cool Party" that has no lyrics at all, which is, of course, a much better choice to go with for the future than something so bizarre like Kerwin White's theme.
#10 "Real American" by Rick Derringer
Lastly, to round out our list, Hulk Hogan's "Real American" by Rick Derringer is one of the most iconic entrance themes tied to a particular Superstar in the history of WWE.
Much like The Undertaker's gong or the opening of "Sexy Boy" for Shawn Michaels, if you hear one split second of it, you know who is coming out from the single guitar note.
Derringer did not write it for Hulk Hogan, though. Instead, it was written for Barry Windham and Mike Rotunda -- the tag team, The U.S. Express.
This makes sense given their name and the whole purpose of the song, but thankfully for WWE history, The Hulkster had a very patriotic angle as well, allowing this theme to mould around him to fit like a glove.
For all his time with Jimi Hendrix's "Voodoo Child", the nWo theme, "American Made" and so on, there's no song that will ever usurp "Real American" as the go-to theme to let the crowd know Hulk Hogan is the focal point.
Unless, of course, you count how Mr. America made this his own even more than Hulk Hogan did, but that's another discussion for another day.
