It all sounds like soft-rock, "I'm a sensitive guy with a guitar" schmaltz to me.
It's not the worst of that species of music, but his giant popularity with the college kids is slightly baffling to me. But then again I'm woefully out of touch with most of what's happening in the music world as it exists for that age group.
EDIT: substitute 'Woeful' for 'Probably Thankfully'
