I don't listen to much of this kind of music anymore, and this is actually the first ATL song I've ever heard, and while I wouldn't listen to it in my car or anything, there's certainly nothing wrong with it. Solid pop tune. So that's my fairly objective opinion on it.
They've made better songs, to be honest. Namely on their first three albums and their Put Up or Shut Up EP. And as Jason said, this is supposedly the worst song on the album.
