Why are some of you fighting over two single artists? They both have tons of no.1s which is easy to make because of Itunes. How can you have so many no.1 s but can't sell a full album? Those no.1s still aren't helping their album sells? People are buying their songs but won't put money on their album. Katy Perry and Rhianna will always be single artists because they have no talent. They can only reach 150k-200k first week with huge promotion. Beyonce's album will still sell and so will Lady gaga's because they are album artists. They also can't sell out tours likr Bey and Gaga.
