Rihanna - You Da One - #14 (Its not a huge flop, but it deserved to be bigger)

Kanye West - Paranoid - #118

The Story of Us
Peak at #41, her only single that fail to reach Top 40.
Her singles always reach platinum, and it's really far from there, maybe about 550k ( Sparks Fly also hasn't reached platinum, but it's close to 900k )

Settle Down, Peak: 32
Dirty Talk, Peak: ? Didn't chart on the Hot 100, pretty sure it topped Dance/Club Plays

Kylie: Get Outta My Way / Timebomb
JLo: Papi / Goin' In

Gaga: "Marry the Night"

Kelly: "Dark Side"

Settle Down, might have prevented the rest of the era from flopping

Why choose I'm a Slave 4 U? Even if it didn't chart high it's still very iconic because of its video and VMA performance. It still got the recognition it deserved. If I was a Britney stan the single I would save is Radar since it's one of her best songs ever

Man Down.
