As I have tickets to see her, I'm listening to a lot of PJ Harvey at the moment. altho I find classical or jazz good for gamedev work when you want to focus on something complex without getting distracted by the song (currently Bitches Brew by Miles Davis, or those Youtube video compilations with 6 hours of Bach or whoever...).
I never really got into Frank Sinatra or the whole swing movement. Did you hear the Sid Vicious cover of My Way? It's certainly different...
