This is really a case by case basis for me. I do my best to separate the art from the person but sometimes that's not possible - Depends on how long and loud that wheel squeaks, and the damage caused, if any.

In this case, it doesn't matter to me how big of an ass Mr. Waters is. I'll still be listening to Floyd on occasion! I would bet/guess The Weeknd (etc.) feels the same about him too!

ETA: Love The Weeknd too!
