Well, I have SOME interest. I believe the first one I ever tried was Guitar Hero: Aerosmith, or something. I kinda started liking real, non-videogame music at the time. I haven't really played all that many afterwards, though...but I know my all-time favorite is Theatrhythm: Final Fantasy and its (admittably near-identical) sequel, Theatrhythm Final Fantasy Curtain Call. As someone whom immensely enjoys Final Fantasy Music, its pretty much perfect for me.
Though, one I can recommend is HarmoKnight. It's a rhythm game...with Platforming! What isn't to love?
