Katy's next album will be whatever Dr Luke tells her it will be. She will either obey or walk. Since she only makes music for the charts, she will obey.
I would agree because of the single but he always manages to build the hype. And it's marketed as the last album on Tha Carter series so idk. It could bomb (500k) or not (+750k-1m)
Wayne won't do 1M. Believe Me was kind of a flop compared to his other leads. Probs 600k or something.
Nicki will do 150.000.
Taylor will do 1M as usual. Rihanna 190 - 220k as usual.
