“IDFWU” has been blowing up the clubs ever since it dropped but we have now learned that the hit single from Big Sean was actually supposed to be for Justin Bieber. The songs producer Mike Free said it was actually created with Bieber’s vocals in mind. “Originally I think Justin Bieber was supposed to have it; he had posted a video of a snippet and everything, where it was him doing the song. They ended up not taking it and Big Sean got the song, and I’m glad, because we ended up getting a really strong record for hip-hop.” Mike said. Bieber even gave the track a name which was “Turn Up” but thankfully this never came to light and we got one of the best diss-anthems of the year because of it.
