It’s a difficult one.
For me, if it’s a solo artist or band member who goes on to commit a horrific crime then I won’t listen to their music any more.
It’s hard to know where to draw the line, though. There’s a band I like called Real Estate and one of their former members left the band due to several allegations of sexual assault. I don’t think he was ever convicted, but he pretty much admitted he’d done wrong. I still listen to the band, but I no longer listen to his solo work. I don’t think it’s fair to penalise the other band members for someone else’s actions. In some cases, though (one of which already mentioned in this thread), it’s just not possible to continue listening to their work.
