I like singer-songwriter acoustic music a little less than the next guy.  It's got to have some guts and passion for me to get into it. 
I like to catch the show Live from Abbey Road when I can.  I remember thinking that I wouldn't like Ray Lamontagne very much based on the whole acoustic singer songwriter thing.  And then he did "Trouble". 
Wow.
He seems like such a unique and interesting character.  I'll have to listen to a bunch more of his stuff.
If you're the impatient type, the song starts at 1:07.
