Fan or not, you have to admit that Beyonce ruled this decade. Any legit list should include her as one of the top artists of the decade. The singles list should include at least one of her songs like, "Crazy In Love", "Irreplaceable", "Single Ladies", or "Halo" (all of which were nominated during its year of eligibility for a Grammy in the Record or Song of the Year categories; maybe she'll finally win in one of those two categories at the upcoming Grammys). Other top artists of the decade include Eminem, Mariah Carey, JayZ, Alicia Keys, Mary J. Blige, and I would have to include Britney Spears.
