Officially no. Realistically yes.

No. The artists I like are pretty much universally good people because they're not wildly successful and had to mature in order to survive. I can't think of a single artist I am a fan of who has done things that would cause me to question the integrity of their character or reassess their work.

Usually people who have this issue are ones who listen to shitty music or like shitty actors that only care about making money and being superior to others.

It's no surprise to me that people like R Kelly pee on teenage girls, or Chris Brown beats women, or David Bowie has sex with underage girls. None of this surprises me because their creations and lifestyles reflect who they are as people. It's always funny seeing their fans being met with cognitive dissonance, though.

I can't really name any actors though because I already don't like the vast majority of shit that gets pumped out of hollywood and I'm not exposed to it often. I'm sure people who are more familiar with their crap will have no problem thinking of examples, though.

Im a firm believer you can like the art and not the artist but if i had to pick it would be the wizard of oz. Honestly what the director did to the actors/actresses on wizard of oz really zaps the magic out of the movie for me.
