Exactly 21 and 4 are dont even belong to the same genre. Congrats to Adele she's doin something thats not be done in like 10 years in music, compare anyone to dat they wont measure up. Race has everything to do with it. Of a black person recorded SLY u wont hear it on pop radio or win a pop category grammy. Lets not even get into the inclusion of Adele in pop categories but when award season comes, they put rihanna, a pop singer in rnb categories. Is this life?
