Dr. Luke's music was pretty basic post TDCC and prior to Prism. Y'all thought he was done in 2013, yet he worked on 1/2 the album with Katy, you all loved it, and it went #1. The same will happen again. Katy will work with Dr. Luke and Max Martin, it will be great, you all will love it (expect maybe 1 or 2 songs), and it will go #1.
Besides, except for Ghost, the worst (least best

) songs are Prism weren't even produced by Dr. Luke!
