Yall are afraid to name. Smh.
My fave is Mariah but not all of her #1s are iconic but she has plenty though.
Vision of Love (Magna Carta of Melisma)
Emotions (the whistle alone)
Ill Be There (this cover ended up being more popular than J5 and is widely used as a cover song around the world mostly in singing competition)
Hero (as sappy as it is, it still is one of the most inspirational song in pop culture)
Without You (same as Ill Be There)
All I Want For Christmas Is You.
Fantasy (the queen of pop/r&b/hiphop collabs)
One Sweet Day (16 weeks at #1.)
Always Be My Baby
My All
Butterfly
We Belong Together, song of the decade.
And now Be Mine.
there are a few more that could be added but I wasn't sure if you could call them iconic exactly
