Justin Bieber, Chris Brown Go 'Up' On New Remix

Bieber and Brown trade verses, harmonize on their Never Say Never - The Remixes collaboration.

Earlier this week, Justin Bieber released the Never Say Never - The Remixes album, which reimagines some of the teenage phenom's songs as duets with some of the biggest names in the business, including Kanye West, Miley Cyrus, Rascal Flatts and Chris Brown.

Brown appears on the mid-tempo ballad, "Up," which is about the power of love and relationships. The R&B star, unsurprisingly, helps put a decidedly more R&B spin on the pop track, which has begun to turn up on various websites.

Bieber kicks off the track before Brown jumps on for the second verse. Brown sings, "It's a big, big world/ And, girl, I'm gonna show you all of it/ I'm gonna leash you with pearls/ From every ocean that we're swimmin' in/ We make the sun shine in the moonlight/ We can make those gray clouds turn to blue skies/ Yeah, I know it's hard/ But baby believe me/ [That we can go nowhere but up]."

By the time the second chorus rolls around, Bieber and Brown are harmonizing and putting their own individual stamps on the song.

News of the collaboration first hit the Web in late December, when Bieber and Brown tweeted about working together, though little more was known about the collaboration then. The 16-year-old said he and Brown had a great time in the studio and that Brown had even given him some sage advice, having been a child star himself and seen the ups and downs of fame at an early age.

"[Chris and I] just talk about regular stuff, nothing too crazy,"

Bieber told MTV News earlier this week. "Just, like, staying humble and remember that God got us in this position, so always make sure to just bless Him and praise Him."

Bieber's manager, Scooter Braun, teased the album and its guest appearances in a chat with fans earlier this year. "Yes, Justin is working on new music," Braun said last month. "He's been talking to Drake about new music. [Bieber] and Kanye had a call today about a song they're trying to work on together; Kanye wants to produce a bunch of new songs for the new album. He's talked with Rascal Flatts. Him and Chris Brown have been sending stuff back and forth to each other."
