Winner: Overall, Timberlake proves to be too much for Bieber. But most of that credit should go to Justin T’s early solo producers. You can’t front on Max Martin’s hit-making credentials. But it will be interesting to hear what the vastly talented Bieber can do when a producer is able to take advantage of his musicianship (he plays both guitar and drums). His Justified is waiting in the wings, but Believe is a good appetizer.
