The guys in fun. haven't made the fact that their 3rd album is, indeed, done and on it's way. And we do know it'll be called "Harsh Lights". What we don't know, is when exactly that'll happen.
For now, we can chew on this.....a new song. Debuted on The Tonight Show With Jimmy Fallon Wednesday night (the 18th). Given 2 or 3 listens, I predict you'll be singing along.
