31. Rihanna, "Unfaithful" (2006)

So this was it.

The song that really made us notice Rihanna.

Her arrival was marked by a sultry slap in the face to the men who thought they were the only ones capable of cheating.

Singer and songwriter Ne-Yo wrote this song and Rihanna rocked it.

This was an ego booster for us ladies who had reached the peak of empowerment.

No, cheating wasn't okay for either side in a relationship, but for once we got to be the ones on the other side of things.

Felt kind of good, didn't it?
