A not-so-subtle tweet from Sara Bareilles this week teased new music and made a lot of fans very happy.

My brand new song is a free download. It rhymes with CLAY, and encourages people to avoid driving. Get it at sarabmusic.com #STAY

Just go to Sara B’s site and tweet or share your love on Facebook to get the free download of “Stay” off her upcoming EP, Once Upon Another Time, due out May 22.

The new song, produced by Ben Folds, has the singer changing things up, going a little less pop and a little more retro.

On the powerful ballad Bareilles pleads with the one she loves to stick around with a little help from a few backup singers.

The 5-song EP is available to pre-order on iTunes now.
