A previously unheard track from Lady Gaga made its way online this weekend. Called "Brooklyn Nights," the song was meant for inclusion on the singer's latest album, "Artpop." Reportedly recorded in the months that Gaga was working on her 2009 project, "The Fame Monster," "Brooklyn Nights" is a pop ballad that has Mother Monster crooning about a failed relationship.

"I always thought it was you / You always thought it was me," Gaga sings in the track. "We always thought we were it / Seemed like a real perfect fit / Those Brooklyn Nights set us free!"

Take a listen to the full demo of "Brooklyn Nights" below.
