It's official: Mark Ronson and Bruno Mars' addictive "Uptown Funk" is now the No. 1 song in America.

The disco-y jam has dethroned Taylor Swift's "Blank Space," which reigned at the top of U.S. charts for seven weeks through the end of 2014.

With 382,000 downloads this past week, the track gives Ronson his first No. 1, although he's co-written and produced several hits for other artists, including Amy Winehouse, Christina Aguilera and Mars himself (2012's chart-topper "Locked Out of Heaven").

Ronson's new album, Uptown Special, arrives Tuesday (Jan. 13) via RCA Records.
