Not all the people included in the round up are best known as performers, with 26-year-old songwriter Skylar Grey - responsible for the hook of Eminem and Rihanna's huge hit 'Love the Way You Lie' - included, as well as producer Benny Blanco, 24, who has songwriting credits on two of the year's biggest singles, Maroon 5's 'Payphone' and Rihanna's 'Diamonds'.
