There are levels of objectivity to art

When people say art is completely subjective I just don't agree. It is MOSTLY subjective but there are levels of skill that people can reach in painting, music, film making, etc that are objectively good. Saying something like "Jimi Hendrix is bad at playing the guitar" can only be born of ignorance to guitar playing as an art form, it's history, and it's evolution. Saying "Jimi Hendrix's playing is not for me" or "Jimi Hendrix is an overrated guitarist" are both reasonable and subjective takes. You may think I'm just glazing Hendrix, but I'm not even a very big fan of his music. I like a handful of songs, but I would actually agree that he's a bit overrated. But bad? Untalented? That's just incorrect. You can't put a number on exactly how objectively good someone is or find an exact line where objective talent starts. It's an imprecise measure but it does exist.
