For Friday the 13th of January, WFMU DJ Kurt Gottschalk played about 20 different versions of Thelonious Monk's Friday the 13th, including quite a few sent in by his listeners. Here's the playlist and 3 hour mp3 stream (below the blinky picture of Monk), including listeners' comments. Good luck!

Covering The Mouse. An MP3 blog dedicated to cover versions of Disney songs. My favorite so far is Gene Simmons' cover of "When You Wish Upon A Star."

The Torontoist Cover Song Catalogue. We tried to avoid some of the more obvious cover hits (like Alien Ant Farm's recent chart-topper "Smooth Criminal") and we stuck with actual recorded covers rather than including those only played in concert. You'll notice that most of these cover versions are pretty chilled-out, which is a byproduct of looking for tracks that were eclectic, odd and often very different from the originals.
