As a matter of fact I happened to be playing Clone Hero just yesterday. The originals were some of the only games I played on consoles, and I seem to recall that Rock Band removed the ability to play using a PS2 controller. I've rebound the controls so my Xbone controller matches what I remember. Plus it's got Linux support, what's not to love?
For my more niche tastes in music, I couldn't just expect Guitar Hero DLC to pop up for it, so I was drawn to the automatic track generators. Audiosurf, Beat Hazard, and most recently Melody's Escape (and by recent I mean this was the first thing I backed on Steam Greenlight). All fairly good in their own way, though I still don't have the knack for Melody's Escape even after changing the colours from Xbox to Playstation colours.
Hatsune Miku Project DIVA is possibly my favourite series, to the point I've got a partially translated copy of 2nd Extend somewhere that supports higher framerates. I've only played the first three and F.
