Beyonce's songs were repetive and they all sounded the same and formula made. They were all about basically the same thing...so even if Kelly's album is mediocre, Beyonce's album was worst than mediocre and it still sold.. so i think it has everything to do with promotion, when BDay was coming out there was alot more promotion then Kelly's..i didnt even kno wen Kelly's album dropped, but everyone knew Bey's album was dropping on her birthday Sep. 4 like 2 or 3 months b4 it dropped.
