I think the Santogold track "L.E.S. Artistes" (scroll down to where it says "key track," and you can stream it) has been floating around blogs for a few months, but it just got a proper release. And I've been playing it nonstop lately. Is it just me, or is this an amazing single?
(I was originally going to link to the video on YouTube, but it's kind of disturbing. You can easily search for it, but consider yourself warned.)
