Aaaaaaall kinda crap!
Metal, hard Rock, Rock, Classical, Classic rock, Industrial (some), Punk (some), Country (some of the older shtuff), Blues, Funk (some), Acid Rock, Celtic Rock, Prog rock (some), Rap (very little), slternative, Indy and a whole lot of others that I am not sure of thier classifications.
I am a high admirer of independent artists. There is so much great music that goes un-known because the artists insist on doing things the old way. They do not compromise thier sound for quick money. They don't take the fame until the people recognize thier music for what it is and not what some corporate suit makes it into to sell to the masses. This is the difference between one hit wonders on VH1 Reality shows and the long term musicians selling out coliseums for 100 bucks a tick (e.i. Rolling Stones, Pink Floyd, etc.)

Come and listen to some of my collection...
