I've been getting really into music games as of late. I really like music in general, and playing fake instruments and jamming on buttons to the beat is pretty damn neato. Anyway, here's the games I can think of off the top of my head. Anyone got any others? Any others on the horizon are good too.

-Parappa the Rappa 2
-Frequency
-Amplitude
-Taiko Drum Master
-Guitar Hero
-Gitaroo Man
-Karaoke Revolution 1, 2 & 3

The Karaoke thing really isn't my bag; I prefer stuff like Amplitude (one of my favorites) and the other games. So if you have any games you can think of, please list them! If you're unsure of whether they fall into the category, list 'em anyways -- I'm interested!
