I listen to alot of music before my time. I have alot of James Browns playlists, classics from the 60s and 70s, I even got some frankie lymon and Louis Jordan shit from the 40s and 50s. I know music.
Jones' overall catalog in multiple genres is extensive, but in rnb alone? He's not even top 3.
This is like voting Kanye the Goat RnB producer.
