For the past six years, NPR Music has held an annual competition to find the best undiscovered artist to come play at Bob Boilen's desk and tour the country with NPR Music. We call it the Tiny Desk Contest. Our five winners submitted videos that stopped us in our tracks and have gone on to do great things, like touring the world and winning Grammy awards. We've included their winning songs, plus other tracks of theirs that we love, on this playlist.
