I run the full gamut...
Right now, I'm on an 'unsigned band' kick from soundclick.com...my favorites so far have been GuitarBoy (blues) Atomic One, Prototype, Big Sky, and Samiam (Sam I Am). Great stuff, and not too commericalized...
I'll listen to just about anything, but Victory at Sea is always in the changer, along with RUSH, Iron Maiden, Megadeath, and some early Metallica...
Course, I'll listen to Elvis, Joplin, Hendrix, or Benny Goodman. It's all good.
