2013 is shaping up to be the year of comeback albums for bands, with the most recent being from Fall Out Boy who released a new single/video "My Songs Know What You Did in the Dark (Light Em Up)." This will be on their upcoming album Save Rock and Roll, which is their first new record in three years. They had initially claimed that as a hiatus, but I wouldn't consider that until more than four years has passed but well whatever. The video features 2 Chainz formally Tity Boi lighting things up and setting fire to pretty much everything. Watch below.
