Heck no. Aretha Franklin is. Janet along with Whitney Houston are tied far as infleuential.

Madonna isn't as good a dancer but she is still a qualified dancer and is more influential overall, so she wins.

It's between Katy Perry and Paula Deen.

When was the last time someone cited Abdul as an influence?

Paula choreographed her two least revered routines (Nasty, What have you done for me lately). Where as Janet co choreographed her most iconic dance routine (Rhythm Nation).

nope

If we ignore Mariah's Heartbreaker video, sure

She is one of the most influential dancers and female pop artists ever, whether people like it or not.

Mariah's dancing

yes, Janet is.
