And not the other 3????

Receipts?

Because it's credited alphabetically and Christina's name appeared first.

Isn't Lady Marmalade only uploaded on Legend X's YouTube Vevo account?

I was actually wondering this. I was looking up the lyrics and it was listed as "Christina Aguilera lyrics"

P!nk has had multiple bigger and more memorable hits since. Xtina doesn't have many other songs that people can associate her with.

All of the other girls have bigger, solo hits

I thought this would ask if it is remembered, which I don't think it is by the GP. But it's remembered as an Xtina song because she initiated the collaboration with the other artists, no?

A Missy Elliott production

I remember it as a pink song first. Then I remember Xtina was yelling on it.

She's the most iconic.

Same reason Moves Like Jagger is remembered as an Xtina song.

I always think of P!nk.
