Based on my countdown, (its in your top 10)
Britney: Radar which peaked at 14

(all Britney songs went to top 5 with 5 of them holding the top)
Kanye: Power (33)
Coldplay: Every Teardrop is a Waterfall (Bubbling under #4)
Chris Brown: She Ain't You which peaked at number 6.

I love Chris' music so you'll never get to see him flop
