Umbrella

Unfaithful

She's not called the Umbrella Chanteuse for nothing

Diamonds
Umbrella
We Found Love
Only Girl
Disturbia
Rude Boy

We Found Love
Umbrella
Disturbia
SOS
Diamonds
S&M

All of them tbh. She's the Icon for a reason.

Umbrella...

Umbrella is her most remembered, S&M as been forgotten and rightfully so.

1. Umbrella
2. We Found Love
3. Diamonds
4. What's My Name?
5. Only Girl
6. Rude Boy
7. Disturbia
8. SOS
9. S&M
10. Take A Bow

Umbrella and Love the Way You Lie are the most iconic
Diamonds and WFL just under that

Edit: I just read the OP, but my opinion stands on LTWYL

We Found Love. That's it, tbh. Maybe Stay and that didn't even go #1

We Found Love was bigger than Umbrella and in the longterm will be far more remembered. Plus Umbrella is basic as hell.

she's called that by the GP about as often as they call Mariah 'elusive'

kind of tea. I do think some of ha other songs are rihmembered though I stan Rih but my gorls Mariah and Madonna already done proved just cos it a no1 doesnt mean the GP will remember it
