(Three Days Grace)
This is well-suited to many situations, but it really brings to mind Donatello in the
Adventures In Turtlesitting / Good Genes arc -- and, of course, season four tough-guy Leonardo :)
Big Man On Mulberry Street
(Billy Joel)
One of the many songs that fit Raphael.
Blaze Of Glory
(Bon Jovi)
For Raphael or Casey.

Leila sent me this one! Mature language in here...
Break Stuff
(Limp Bizkit)
Sent to me by Dawn for Raph when the old site was active. Mature language here, too :)
Brother My Brother
(Blessid Union Of Souls)
Sarah sent this one in for Leo and Raph years ago. It also seems to suit Mike and Leo's relationship
(as well as Raph and Don's) in the recent chapters of my story, "Far From Grace"

Pretty much just what it sounds like. Good song all-around for the TMNT.

Flash Of The Blade

Fooling Yourself (The Angry Young Man)

This could be Raphael's theme song ;)
Footprints In The Snow
