Spurred on by one of the sites I read, I figured I’d count up how many languages are represented in my music collection. I found nine, though I may be off. Some of the J-Popish stuff I have no idea what language it is, especially the Arjuna music (which is often 3-4 languages in one song).

English — duh
Japanese — lots of stuff, most of it bad
German — 99 Luftballoons
Afrikaans — 1 Giant Leap
Spanish — Some Manu Chao my friend Gabe gave me
Galican — Manu Chao again
French — some Avalanches stuff, I think Manu Chao too
Korean — A couple of DDR songs
Latin — the obligatory chants, One Winged Angel and Carmina Burana, among others
