Here's a little update regarding the Prince tribute. It's released by Rex Records and the artists performing the songs are mostly from the electronica genre. They've also put up a website with MP3 samples:

The tracklist looks interesting, by the way. I've had the version of TMBGITW for a while on promo now, and it's great. At least if you're into electronic music at all.
