Beyonce (6)
BEYONCE (6): Beyonce won five awards in 2010 for 'I Am ... Sasha Fierce' in R&B ('Single Ladies') and pop ('Halo'). For Beyonce, "taking on an outside assignment put her in the record books," says Grein. She earned extra credit for 'At Last' (from the 'Cadillac Records' soundtrack), which brought in the sixth award.
