This is another strong category, with nominees like Cee-lo Green, Bruno Mars, Rihanna and Lady Gaga, but the singer with the strongest album among them is Adele's 21, hands down. I am only beginning to like her work and the more I listen to it, the more I am more enamored of her. To think, I am already familiar with her earlier work in 19. But this album is a quantum jump from there!
