Don't really have a favorite genre, tbh. Though, for the moment I am into jrock mostly but not the heavier bands D:. I also like DnB, breakbeat trance, Korean hip-hop such as epik high and others. I'm also getting into some jazz. Oh, I do listen to Chinese Pop too like Jay Chou or Wilber Pan from time to time too.
American rap/hip-hop/r&b (or trash as I call it) never seemed appealing to me. I did like a few American rock bands, but I've never found one that I've stuck with for too long.
