The band has to renegotiate their contract with the record label. The band is absolutely stupid when it comes to this and acts like they can't understand all of the legal "mumbo-jumbo" involved with renegotiating their contract. However during the Season 1 episode "Bluesklok", the band understands negotiating a contract like it's the back of their hand. So much so that the devil wants nothing to do with them after they made a few amendments to the devil's original contract.
