Scooter Braun has told MTV that the songs Justin Bieber did with Kanye West and Taylor Swift were basically a bit rubbish so didn't make it onto 'Believe'.
Talking euphemistically about the songs 'not making sense' he said of the Swift collaboration: "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 Kanye track, meanwhile, "didn't make sense at this time" either.
Bieber also wanted to work on some songs with Adam Levine (who wouldn't?!?!?), but no one could get their shit sorted out in time.
"We talked with Adam Levine about doing stuff," Braun continued. "And he wanted to, but with everything else, we could just never get the studio time in together."
