Justin Bieber completes his Journals collection with five new songs. In addition to his #MusicMondays collaborations with R. Kelly and Chance the Rapper, the pop heartthrob enlists Big Sean (“Memphis”), Future (“What’s Hatnin’”), Drake (who penned “One Life”), and Lil Wayne, who guests on “Backpack.”

Biebs sings about protecting his extraterrestrial friend, played by Weezy, who crash lands his flying saucer to take over the planet.

“I’m an alien/ My swag is out of this world/ Different galaxy, they try to capture me/ When I die, they gon’ name this planet after me/ Wayne’s World,” raps Tunechi over a wailing electric guitar.

Journals is now available on iTunes and you can download a sixth new song, “Flatline,” for free.
