Considering that last post I would be remiss if I didn't make the Song of the Day Bobby McFerrin's "Drive My Car" from the Simple Pleasures album.
Though I'm not entirely sure if this cover of the Beatles original is Jazz or Pop or what, I do know that it's a catchy tune. And like the other works from this remarkable artist all the sounds on the track are his voice or hands (maybe feet, too, but I don't want to imagine further than that). No man-made instruments of any sort. The astonishing vocal abilities of Mr. McFerrin are enough to impress anybody, but his ability to blend poly-rhythmic arrangements that couldn't possibly have been put on sheet music into one complete song is mind boggling.
