You've probably caught yourself wandering around the streets singing "tonight, we are young/so let's set the world on fire/we can burn brighter than the sun". It's even okay if you've thrown your hands up in a grandiose way to accompany your solo jam time.

Now, they're headlining their own tour (get your dates here). Let the fun. begin!
