What theme music I would use for myself if I were a wrestler is something I've thought about for a long time. I've actually updated it over the years. I've had four in mind and the first three haven't been mentioned yet.
The first is "My Way" by Limp Bizkit. I would start it out with the part where they go "YEAH!" Right before the chorus and have pyro go off, then I'd come out.
Second was "Papercut" by Linkin Park. It's a very tiny bit like rap, but it's metal rap so i think it would work. I actually used it as my entrance in Raw 2's create-an-entrance (just about the only thing that game was good for) and it worked pretty well. I used the Dudleys' shooting star-like pyro to go along with the music at the beginning and it was awesome.
The third was "Meant to Live" by Switchfoot. That would definitely be better suited for a face though. I think the way it begins really works for an entrance theme, and I was thinking it might work with a Chris Jericho-like entrance.
And my current ideal entrance music has been mentioned twice. "Stricken" by Disturbed. But I disagree with it only being suited for a heel character. Think about it, songs that start and go on for a little bit before the guy comes out at an impactful moment in the song are great for face characters, such as the DX theme, Undertaker's theme, Batista's theme, and John Cena's theme.
With this song, the music could start from the beginning, and then when the Disturbed guy does that yell the superstar could come out and the crowd would go nuts.
And I think the best way to walk down the ramp with that song would be the way Steve Austin would walk.
