And I don't need to watch a video to know that statement is utter BS. Songwriter? Ok, maybe you can make a case for that. But I don't care what metric you use, KC was nowhere near even one of the GOAT.
One can make a good argument for lots of players out there, as long as you qualify it with "one of" or, "my choice", or something like that. Unless it's EVH! Haha
To a degree, I think anyone who can effectively communicate their music is great, regardless of the technical ability, but that’s more songwriting than it is guitar playing and if there’s one thing guitar players have shown us, there is a huge divide between guitar players and songwriters.
