Agreed, he is a very rare talent. He killed his lane and is the prototype for a lot of these "singing" rappers.He is not a tough placement, because he killed his category hands down.
He went from Byrd Gang/Dipset to Coke Wave w/ French Montana to just being Wavy.
You don't kick out that many songs with so many memorable moments without being a rare talent.
But his category is difficult to place with the rest of hip-hop. Wavy is it's own genre almost.
