I'll have to agree with 21lux. New songs don't interest me that much, and I'll usually look up songs that I've heard my sister play or something. I guess that's why I like songs from anime since I've already heard it before.

I actually listen to many different genre's and artists, and I don't usually mind when artists change styles. Though there is one Vocaloid artist whose new stuff sucks. It's a shame really.
