If you're looking for bands to listen to, go here:
CureMedia U.S.A - PURE J-ROCK
and click on "Listen Live".
Also, if you're in the US, the US iTunes store has been getting some Visual Kei bands, and practically all of Matenrou Opera and DELUHI's music is on there for a reasonable *understatement* price. There's also D'espairsRay, Girugamesh, Phantasmagoria, DuelJewel, Versailles, Vidoll.... I don't listen to all of those(I already posted the ones I like the most), but I just thought I'd mention that they are available at the US iTunes store, and there are other bands I didn't mention.
*EDIT: Ok, so the site I put STILL works, but they have another one, and it's the one they will be using from now on, so here it is:
CureMedia - Visual Kei J-Rock One-stop Site
