Its called Kick Ass from the movie soundtrack and its by Mika and Redone
During the opening credits the song played is Stand Up by Prodigy.
for the end credits I copied and pasted this from IMDB after confirming it to be true:
Make Me Wanna Die - The Pretty Reckless: Red Mist turns around and and says: Wait until they get a load of me! and end credits starts
Kick-Ass - MIKA: Second song playing in the end credits

Yes, you have to stay after the credits and there will be an ending leading to a sequel
KISS - Love Gun
Go to Ear-tweak.com and select 'The Music' to see all the opening and ending theme songs used in the show. (If you look closely enough during the credits [somewhere in the beginning I guess] you should see Ending Theme and underneath it will be the name of the song playing).
15 Steps by Radiohead
Im pretty sure it plays New Divide and What I've done by Linkin Park.
"Where is my Mind?" by the Pixies played at the end of the movie Fight Club. The music starts when the buildings begin to explode and it continues playing during the ending credits.
In the ending credits, the song is called "Birdie" by Angela McCluskey, Kevin Salem, and Brian Kelly. See the related link.
Tna by white beaver.
If you watched the movie in theaters there were no ending credits.
