rih and katy aren't even comparable. rih has a rich back catalogue of great songs (by prerogative of the amount of material she's released slightly). i mean, i may be one of few people on atrl who admit that unlistenable is trash but katy doesn't have anything nearly as great as numb.
she has like, what, spiritual, birthday, lfn and hot n cold. rih has that on rated r alone
