Hollister Song

I was recently at Hollister, and heard a slower, more relaxed song than they usually play...unfortunately, all I can remember is the chorus which barely has any words in it. It's just a guy singing "oooo oooo, oooo oooo (yeah that's right)" with some light guitar in the background. Any help would be appreciated.

It sounds like it could be a song by Dashboard Confessional. Was it like an acoustic guitar and was his voice like a tenor raither than lower like a bass or baritone?
