She was entertaining.
I don't think she had a strong voice,
but the fact that she knew her lane made her talented.
Plus, the music she made was really good.
She was a vessel for Missy's vocal arrangements and Tim's production.

Jimmy Jam even said that Janet Jackson wasn't the strongest singer,
but she had a voice you felt like you could sing with.
That's what made her popular.

I see Aaliyah in the same vein.
