Alicia Keys, "One Thing" (2012)
Ocean's star rose rapidly in songwriting circles after he started putting out his own music. Alicia Keys recruited huge names to help her craft the Girl on Fire album: Babyface, Dr. Dre, Jeff Bhasker and Rodney Jerkins. In the midst of these titans, Ocean managed to place a song he wrote with Keys and Channel Orange producer Malay. Keys wasn't planning to write when she met Ocean. "We were just gonna hang out and talk and next thing we knew I was like, 'But I have these chords,'" she told MTV.
