Mark my words .. Her next album won't even sell 25% of what TD did Katy and Rihanna are BOTH single artists .. #Deal Katy's last album sold more because she had several hit singles (thanks to Dr.Luke) NOW, through Katy we can see what will happen to Rihanna if she takes a break .. She will FLOPPPPPPPPPPPP A first hit single = good debut week album sales ... FALL .. DROP .. FLOP .. THE END.
