Justin Bieber, Lil Wayne Blast Off on 'Backpack': Listen

Justin Bieber

Justin Bieber's full collection of "Journals" has arrived on iTunes as of Monday (Dec. 23), with the 10 songs included from the pop superstar's 'Music Mondays' release series as well as five new goodies for Beliebers. One of those new tracks is "Backpack," an intergalactic R&B saga featuring a man who has long claimed to be a martian: Lil Wayne.

"You said 'I come in peace,' so I took you home," Bieber begins, huddling an alien being into his backpack -- and for those who think that this narrative is a metaphor for a romance, the pitched voice crying, "No, I gotta find my spaceship!" pretty much negates that theory. Later, Weezy pops in as the alien in question, rapping, "I'm in the backpack/I'm ducking Men In Black/Yeah I'm an alien, my swag is out of this world."

Along with "Backpack," the previously unheard "Journals" songs are "One Life," "What's Hatnin'" featuring Future, "Swap It Out" and "Memphis" featuring Big Sean. "Journals," priced at $13.99 in iTunes, also includes a video for "All That Matters," a trailer for his upcoming "Believe" film and a clip titled "Guatemala Pencils Of Promise Journal," which shows Bieber helping to build a school in the Central American country.

"this music is everything to me. happy to finally have it all out to u. it is all about the music," Bieber posted on Twitter on Monday morning. On Wednesday, Beliebers get another Christmas gift when "Believe," the follow-up film to 2011's "Justin Bieber: Never Say Never," hits theaters.
