What do you use to listen to you anime/jap pop music?

I tend to just watch anime and download songs from the series that I like and then search out other songs by the bands. I use MusicMatch Jukebox as my media player since Limewire is a massive pile of shit that lags during songs if I surf the net and the screen needs to load at all (not to mention that downloads fail all the time). I download anime OSTs every once and a while too. Last one I got was BECK because Chiba has an awesome voice and their cover of "I've got a Feeling" was about 100 times better than the actual version by the Beatles.
