What happens when a song just takes you over, and you hum it all day long? That's easy. It infects you like a virus. It infects you like Mouse Rat. The Rat takes inspiration from the greats - Dave Matthews Band, Counting Crows, and recent (but solid) discovery Train - and then spins it out of control.
This is why Mouse Rat is Pawnee's #1 band for any music event, and all unofficial government functions.
