If you don't already use this, try Pandora Radio while you write. I think it's good for inspiration. What you do is enter either your favorite singer or song and the program will play songs that have been judged to be similar to that one. It's free!!!
Right now, I'm listening to songs by or similar to Johnny Cash because he's a badass and likes his drugs, good for the character I'm working on right now.
It's a pretty good program, I've put in some somewhat obscure artists and the program was familiar with them.
