Is there any reason you wouldn't want to listen to a Juicy J remix of a Passion Pit song? The answer, of course, is "no." You can stream the official remix of "Constant Conversations" from last year's Gossamer in the replies.
I'm actually so stoked to listen to this. Juicy J is an awesome producer, his beats on Mystic Stylez are some of the most evil trill shit I've heard in my life.
