Weird, But Interesting Music - Internet Radio

I know I've posted about this on my Facebook status before (and, since these posts get sent there eventually, this will be too!), but I'm currently listening to some interesting stuff while I'm at my desk working. It's on the Shoutcast Internet radio network, and it's the "Polskie Radio" New Age & World Music station, using Winamp.

What's most interesting on this station? Apart from the various Celtic and other New Age music that I've always enjoyed, it's very interesting to hear "popular" music in Gregorian Chant. Chant versions of a Cure song, Eric Clapton, REM, and many, many others. It's quite an interesting take on the songs.
