What is this song? Please Help me. Its a recent Indy rock song?

It sounds like The hoosiers/Fallout boy/Panic at the disco type band. and the only part I can remember is the chorus, which is really catchy, and just made up of: Baa ba ba ba ba ba ba ba baaa ba ba ba ba ba ba ba. There is a b guitar and a piano in the background. I have scoured the net for this song, but as you can see...ba ba ba isn't alot to go on. My friends don't know from me humming to them either.
