In reply to Tyler Makiavelli.

Ray of Light may be one the greatest pop album and Madonna may have better quality pop music than Janet but overall Janet soul and r&b productions is way greater then anything Madonna ever produced.

Janet impact isn't in the terms of her success but the way people used her sound.

the 90's R&b/ New Jack Swing was based mostly off RN1989 and Control productions and melodies.

Velvet Rope also help Neo Soul commercially viable.
