A new song from Foster the People leaked on Tumblr late Wednesday night.

The new cut, titled "Best Friend," is a jittery, disco-y jam that sounds ripe for the dance floor. It is expected to appear on the band's forthcoming new album, Supermodel, which arrives March 18 on Columbia.

The band debuted "Friend" and other new tracks for a BBC Radio 1 session, which includes other tracks that can be heard here.

Listen to "Best Friend" below (for now).

UPDATE (02.21.14): The song has leaked again (as in, for the second time) after disappearing from the Net.
