Beyonce's upcoming album 4 is years on the making. She's been reported to have recorded 72 songs for the release. The task at hand: dwindling down the songs that will make the cut. In her Billboard cover story, she revealed she had many different sounds on there and was influenced by everything from Fela Kuti to Florence + The Machine, Prince and more.
No concrete date has been set for the album as of yet, but rumored collaborations include Odd Future, and Sleigh Bells so far.
