Not anime, but Japanese music.
Who has Itunes/Ipod? I do. You can get Japanese rock off from it if you switch the store to Japan (at the bottom). Of course with their restrictions, you cant buy from the Japanese store... but you can buy the itunes card! For either 1500 or 3000 yen. >.> From http://www.jbox.com/SEARCH/itunes
Just thought Id put this up here.
