[PAPER2D] Songs and Attentuation

Hey guys,
I am getting really into the making of my game and I even recorded my own background music and I need one of these songs to play over the whole map only until the player gets near songs that have an attentuation set on them. How do I make that happen? Also, the songs need to be in a constant loop and for some reason, there is a slight break in between the loops, how do I fix this?
