RCA need to milk her more next time. If she releases the next album in 2 years, she'll flop even harder just like Xtina did. She needs to release an EP with rock outtakes from Warrior this year with a lead single better than Tik Tok + Die Young. She has like 5(?) more albums to record with Dr Luke and release with RCA, so she might as well get them over with fast (Rihanna style) and build her star up again.
That's the only way I can think of that would revive her mainstream career.
