Stupid Girls flopped? Such an iconic song/video.

You're Eternal. Mariah needs to stop rehashing.

Katy Perry, "This Is How We Do"
Ariana Grande, "Put Your Hearts Up"
Taylor Swift, "22"

CK tbh.

Mariah Carey - Eternal
Demi Lovato - Made in the USA
Selena - Falling Down
Ciara - Never Ever (though i wouldnt consider Cici a pop gril)

GUY by Lady gags the video is really really good tho

Beyoncé-Pretty Hurts

They aren't in the OP. But they're lower tier disney girls that consistently flop anyway.

Some of these are such good songs

Rumour Has It is not one of them.

How this is a flop when is like 2x Platinum + went top 20

This went gold before it was even a single, bye

-

G.U.Y is my least favourite out of these.

Nicki Minaj, "The Boys"
Ke$ha, "Crazy Kids"
Lana Del Rey, "West Coast"

I'm going with G.U.Y because i remember that being messy

You forgot:

Lady Gaga "Marry The Night"
Shakira feat Rihanna "Can't Remember to Forget You"
Taylor Swift feat Ed Sheeran "Everything Has Changed"
Taylor Swift "The Story of Us""
Rihanna"California King Bed"
Rihanna "What Now"
Rihanna "Right Now"
Katy Perry "Birthday"
Ke$ha "C'mon"
Mariah Carey "Beautiful"
Beyoncé "Run The World (Girls)"
Miley Cyrus "Adore You"
Demi Lovato "Neon Lights" "Made in the USA"
Selena Gomez "Slow Down"

And Lana isn't a pop star and Put Your Hearts Up doesn't count. I don't know I think it's a bit harsh to say songs that peaked within the top 20 flopped (Selena's singles sans Come and Get It would all be flops by that standard).

Mess.

Anyway, voted for TIHWD + XO + 22

GUY. I think it has also the biggest budget but sold less among the choices.

guy flopped harder than all the other songs combined

Oh and:

Jennifer Lopez "First Love"
Jennifer Lopez feat Pitbull "Live It Up"
Jennifer Lopez "Dance Again""
Jennifer Lopez "Goin' In"
