Musical Geniuses...

Imo most are non-rappers, but there's no traffic in 'r&b alternatives' sooo...do any rappers fall into this category?

For reference, some musical geniuses of all genres imo:

Prince
Michael Jackson
R. Kelly
Quincy Jones
Stevie Wonder
Kanye West (Yeezus doesnt discredit his history)

Imo only a few other rappers/ producers can be called 1
