I listen to Bulgarian folk music once in a while.
I have a VHS tape of a PBS special about Mongolian Throat singing, it sort of grows on you.
I love the sound of the Didgeridoo, but I don't know if there are any albums available...national geographic's tv show is where I first heard of them.
I love Enya, and a few of the other Gaelic/Celtic artists, just reading the song titles is challenging, let alone trying to understand the lyrics.
Rammstein, a friend from Austria got me interested in them, I like the German vocals it fits with their sound, same as quite a few other Austrian and German bands as well, but I don't remember their names.
