Try FRED, or the stations around it. Mostly rock. Since they added stations and since I haven't had my car in over 4 months, I can't recall the station# of the top of my head...I think it's in the 40's though.
I listen to FRED once in a while, along with Squizzle (SP), Boneyard, as well as the other rock stations, and I still have a hard time finding good music overall on this catergory. Once in a while I will switch to Jazz,Hits, or Urban.
