Nicki minaj should be included because all her raps talk about the same boring stuff like "I'm slaying these hoes" and "I have mad money" blah. it's just as boring to me as a ballad and since she does pop music...
By far Taylor Swift, if she's not releasing some boring country song she's doing a generic pop typical thing.
And that's without talking about her boring personality, I could barely see a minute of her Apple interview, seriously what's wrong with her.
I feel Beyoncé's is. Most of her album tracks are filler R&B songs with only a few good standouts on each album (excluding 4, her only solid album IMHO).
