Katy Perry

omgg nickiii she would kill anyone coming her way this is what I NEEEEEEEEEEEEEED

Nicki doing hardcore dark rap would change the ENTIRE game.

Oh dear.

Nicki's dark era would be crazy.

Katy.

Can't see the other two doing it.

I feel like Ke$ha could really surprise people with her own 'Let Go' type of era.

I wanna say Ke$ha. I like her songwriting and her dark era could be like her more personal songs: Dancing With Tears In My Eyes or The Harold Song, etc. I'd totally be here for that.

Nicki's. This is what I want her to do next.

A whole roman holiday album, mhm this would slay

Nicki could never. Her lyrics never seem sincere, nor they do they have any kind of depht in her delivery.
I'm on the fence with Katy, since her attempt at dark on TD failed miserably (CTD), but that said, she maybe could follow the formula her "Black & Gold" and "Electric Feel" have.
Ultimately, I will vote for Ke$ha basing my decision on her Dylan cover.

Ke$has dark era will prove her credibility as a writer and maybe even vocalist. She's got it and she will show it. The boobs can only take you so far before the deflate

I don't know. She said she thinks her next album will be mostly Hip-Hop, and I think she'll do some crazy things.

She has the talent to make some crazy ass ****.

I'm sorry, but Katy's upcoming dark era seems like it's going to be a disaster

Katy for sure. I don't see it happening but she could do it if she really tried. She has the best chance, I just don't see her getting too dark. It would not sell well with her established fan base.

Ke$ha has some dark-ish songs, but she could never have a dark era, she's the party girl. I just don't see her getting that dark. Maybe more mature on her next one though.

Nicki is just too much of a joke at this point. I am not here for her trying to be dark...
