Im flexible in this department. I listen to "good music", regardless of genre. The ones with the bulk of what I enjoy tend to be Classical, "Video Game" music and some "movie" music, as well as some comedy music produced by Johnathan Coulton and the Arrogant Worms. I also enjoy some of the music used for anime openings as well. There seems to be something about them that seems more unique or creative, I dunno.
