It's stunning to me that Katy Perry, after ruling the singles chart for most of the decade, gets away with having such flat sales numbers. Shouldn't she be up there with Adele and Taylor Swift numbers, considering? These are not good numbers for someone who is considered a premiere pop star of the day. These numbers would only be ok for some B-level pop act. Unless, of course, that's what she actually is behind the glare of marketing and manufactured hype...

Hmmm.
