I'd like gaga if she changes drastically.

I would like Katy Perry if her personality wasn't that of an annoying braindead bitch and her fans knew what's her 'place'.

oh

I can't excuse Nicki for her recent try-hardness but her songs I can actually enjoy

I'd like Rihanna more if she was a much better live performer than she is now.
I'd like Katy Perry more for the same reasons as Rihanna, plus if she made less generic music.
I'd like Britney if she could just sing live and not perform like a zombie.
I'd like Nicki Minaj if she went hard with her music like she did on "Monster".
I'd like Justin Bieber if he were a better singer/performer and made music that actually stood out.
I'd like Drake if he stopped rapping and stuck to singing.
I'd like Taylor Swift if she didn't write songs like a pre-teen.
I'd like Lana Del Rey if she were a vastly better singer-songwriter than she currently is and didn't have such a lackadaisical attitude about her career.
