Demi Lovato led a crowd of emo kids in a cover of Paramore's 'Misery Business'

Demi Lovato was a guest DJ at Emo Nite in LA on June 6, blasting the finest anthems for the broken hearted MySpace youth quoted religiously on their profiles.

But the speakers went out (a very emo problem) but Lovato, who is the business of misery, handled it like a pro. Lovato led the crowd in an a cappella cover of Paramore's "Misery Business" and everyone absolutely crushed it.
