Keri Hilson has a UK #1
Ciara has a UK #1
Nicole Scherzinger has a UK #1
Ashanti has a UK #1

I'm glad all my faves are so successful.

Those stats for weeks in the top 40 aren't right. Even really massive hits rarely spend over 30 weeks in the top 40. Those might be about top 75 or top 100.

Coldplay: 2
Muse: None
U2: 7
Foster The People: None
Paramore: None
Evanescense: 1
Radiohead: None

- I Kissed A Girl
- California Gurls
- Part of Me

Rihanna - 7

Although Don't Stop The Music and Rude Boy and Russian Roulette should be on the list.
Take A Bow and Live Your Life are forgetable she has so many better songs then those, so I can't believe those got to #1. But anyway 7 UK number ones is great
