Mark Ronson has been producing great hits forever, and he was a big friend of the late Amy Winehouse. Now he has a new single that's all his own. “Uptown Funk” features the soul king himself Bruno Mars.

“Uptown Funk” is the lead single from Mark Ronson's new album, and that album is slated for release next year. CBS Radio label this song as the greatest of all time. That's a tough billing to live up to, but we can't stop tapping our foot whenever we hear it.

It is really funk, as you would expect from the title. It's very a grindy tune, and it's really fun to listen to. But then again, we'd expect nothing less from Bruno Mars. It's a 70's jam that will get ya movin'.
