Justin Bieber and Taylor Swift Collaboration 'Didn't Make Sense'

Justin Bieber hit the studio with many artists in preparation for his album Believe.  Why didn't some duets not make the cut?  Bieber had recorded with Kanye West and girlfriend Selena Gomez' BFF Taylor Swift.

Bieber's manage Scooter Braun explained to MTV News, "It didn't go on Believe, because there's another record they want to work on. So, it just didn't make sense at this time, and the song they did just didn't make sense on this album."

The songs can wait, since these artists are not planning to stop putting out great music for their fans.    

Will we ever get to hear these unreleased tracks?
