None. Those of us who aren't Microsoft supporters still don't get any real music, with the solitary exception of BTBAM. One offering, from a multitude of decent bands available. Disappointing, to say the least.
We still haven't seen 3IOB, Skeletonwitch, WOP, or Unearth, and we probably won't see Arsis, JFAC, or Evile, either. It's kind of a bummer that something that seemed like such a rad idea is reduced to so little for PS3 owners, limited choices, taken from a barrel of primarily talentless bands that present little to no challenge or entertainment.
Go Billboard charts and public radio, may your decades long, sheep-wavering sacrilege against talented music reign forevermore. And to hell with Sony for their hand in us not having any selection besides half-assed hard rock and ability-lacking hacks who became famous 'musicians' by flaunting 'good looks'.
