Hot Song: 'I Won't Give Up' by Jason Mraz

Jason Mraz's "I Won't Give Up" (Atlantic) is destined to be a smash across multiple formats -- a simple, timeless ballad that is immediately recognizable and completely memorable. The acoustic version (there's apparently also an electric version that may end up on his forthcoming album) balances the tender chorus ("I won't give up on us, even if the skies get rough. I'm giving you all my love. I'm still looking up.") with a slicker chorus that should keep all sorts of fans happy.
