Edge's
Beer Money's
AJ Styles's
Evolution's

No, stop laughing. Dat guitar!

I like Cult of Personality when Punk's using it, and I love Hey Sandy by Polaris, Chuckie T's old theme song, but for me, my absolute favorite theme song is Edge's theme song, it never fails to pump me up. Also, the into to the Main Event Mafia's theme always make my heart pump because they were right when I started getting into wrestling and I HATED them.

RVD's WWE theme
Marcus Cor Von
Wyatt Family
Kane's 'Slow Chemical' one
Taker when he was using Ain't No Grave
CM Punk with Cult of Personality

These are all judged according to how awesome it probably feels to walk out to them.

Cult of Personality is pretty good, but I much preferred This Fire.

^ Agreed, it fit him so much better.

and wow, if I listed my favorite wrestling themes, I'd be here for like months... I like too many, I'll try to list off the top, but I likely forgot most of them.

-Both of CM Punk's themes (I liked Cult of Personality wayyyy before he used it too, so I'm a faggy Hipster. )
-Batista's theme (I walk alone)
-Orton's old theme (burn in my light)
-Edge's Metalingus
-Chris Jericho's theme (break the walls down)
-Mark Henry's theme
-The Miz's new theme (I came to play)
-We Are One (Nexus theme)
-Shield's theme
-Ryback's "Feed me more" theme
-Drew McIntyre's Broken Dreams
-Sexy Boy (HBK)

Ehh I'll stop there, but there are wayyy more.

Wow...

Edge's, CM Punk's (both, but "This Fire" was the best imo), Kane's "Slow Chemical" (damn, that one was really awesome), Jeff Hardy's old WWE theme, London/Kendrick theme (when they were teamed up), Jericho's, Chris Masters', Drew McIntyre's, Beer Money's... Hell, even The Ascension have an amazing theme and entrance! They could be amazing heels if WWE didn't screw them with a shitty gimmick...

There's a huge, huge list I could paste in here lol
My favourite has to be CM Punk when he was coming out to "This Fire". Especially during the Straight Edge Society angle.
