YAS, Beyonce is capable of anything. A lot of people doubted her during the 4 era, and thought she was over, but when she came back selling more albums than any other pop girl, she proved everyone wrong. If Bey really wanted to have a huge single like Single Ladies, she could've promoted Drunk in Love hardcore by going to every Entertainment tv show, but she didn't. She still end of achieving success by Drunk in Love peaking at number 2 just from performing at the Grammys alone.
