I know a few good pages with free anime music. They are worth checking out. Totally free and no risks at all.
gendou: This page requires registration, but it's free and unlimited dopwnloads from anime only. There are certain animes that'll never be posted bacause of license rules. Easy design and no pop-ups. Good variaty of songs. >

kh-insider: A lot of soundtracks from anime, live-action and games are assembled here. no registration. Simpley choose an album from the list, choose the song and start downloading. No registration, only a few pop-ups no risks at all. >
Check it<
ff-shrine: ff-shrine also contains soundtracks from live-action, anime and games. It basicly the same as kh-insider only with a few more ads. Again a good variaty of soundtracks, no registration and no risks. Same system as on kh-insider. >
