Justin Bieber unveils new album's track listing via Instagram murals

Bieber had a mural painted for each song by a different artist in a different city around the world, and then uploaded all of the photos to Instagram in one big posting spree.

Each pic includes info on where the mural is located plus the name of the artist who made it, and Bieber is hoping Beliebers will have fun tracking down the art.
