because all of her videos are shot in a mall

Even if I'm not a big fan of her music, I can't deny that Katy has the best vídeos. And the most original.
Pink's vídeos are underrated just because they aren't "flashy", but she has amazing videos.

Where the hell is Bjork? I mean these videos...

Lady Gaga

Nicki, Gaga, Katy, Rihanna, P!nk

If you didn't at least vote for Gaga, Britney, and Rih, you're wrong.

Britney, Katy & P!nk

JLo, Pink and Rihanna

Where is Lana????

I voted for Britney, but not GaGa and Rihanna.

GaGa and Rihanna have made some great videos (Telephone, Disturbia, We Found Love) - but with GaGa a lot of her videos are very scary or just strange. With Rihanna she is hit or miss. She can make a very epic video for one single and then make a totally crappy one for the next.

I voted for Britney, Katy & P!nk because they are the most consistent in putting out good music videos.

Rihanna and Lady Gaga

Out of these; Rihanna, Gaga, Britney, Beyonce, Pink, Gwen.

Gaga slaying radio, critics, and ATRL polls. A true phenomenon

Rihanna - the We Found Love video

Gaga - The legend that is the Telephone music video.

Nicki + Rih

Britney Spears or Madonna

Madonna would be the true winner if on here. I know she has time on her side but she truly has the best videos over all. And they inspired so many of the artists on this list.

Katy, Gaga, Rihanna, and Britney.

Definitely Miley.
