Ashanti and Christina Milian were often the track singers and songwriters. "On the 6" was where it's most obvious but the thing to bear in mind is she was with P Diddy, including at the club incident where someone was shot and another person took the fall. So a lot of "her" music isn't hers, just produced and paid for by a now imprisoned creep and wrong'un but had a lot of power and connections then.I bought one of her albums in the early 00’s and all of the tracks were mostly backing singers carrying her. She was effectively doing a Milli Vanilli. Not sure how she managed to get away with it?
She was always a dancer and that's how she first got famous with "In Living Colour" as a back-up dancer but she's managed to spin silk out of tit through very little that she comes by naturally in terms of talent.
For funsies, here she is in Janet Jackson's video from 1993.
