Artist/Song Title?

Last year, I was in a restaurant, and they were playing alot of good artists...people like Lamb and Gorillaz. Well, there was this one song that caught my ears. It sounded a little jazzy, but I'm pretty sure it was a trip-hop song. The only part of the song I really remember is something like, "You leave, you stay" and something about returning. Does anyone have any suggestions?
