Justin Bieber Reveals ‘Purpose’ Track List Via Graffiti Art Around The World (PHOTOS)

Justin Bieber's upcoming album "Purpose" will boast 18 new tracks plus a bonus song with Ariana Grande and the pop singer has revealed the titles of those first 18 songs through some artistic promotion tagged across the world.

Bieber had graffiti artists tag the titles of his songs in cities around the globe on dividing walls and the sides of buildings. He posted photos of each spray-painted title on his Instagram as well as the cover art for "Purpose," which drops on Friday, Nov. 13.

"Thanks to all the artists who stepped up," he wrote on his Instagram.

The "Boyfriend" singer has gone to great lengths promoting every part of this album, his first since 2012's "Believe." He had celebrities pose with the question "What Do You Mean" in the weeks leading up to the single's release and traveled around the United States and Europe so far to get the word out.
