Sara Bareilles’s latest single is the song “Uncharted,” and like her entire album, Kaleidoscope Heart, it almost didn’t happen.  While working on the album, Sara got a really bad case of writer’s block, and she told Vh1 Radio Network that it was actually the penning of “Uncharted” that got her through it.

Here’s Sara's take on the meaning of the song...

The video for “Uncharted” features guest appearances by a number of different artists, including Adam and Jesse from Maroon 5, Ryan Tedder, Pharrell, Ben Folds and more.

Sara's album Kaleidoscope Heart is in stores now.
