Hazel Dickens has a song called "It's Hard to Tell the Singer from the Song" and, if that's at all true, then a musician's character does indeed matter.

I know for example, that some people think highly of the music composed by Richard Wagner. But Wagner was also an anti-Semitic essayist whose writings were influential on Adolf Hitler whose anti-Semitism led to the genocidal murder of 6,000,000 Jews (as well as the murders of millions of Gypsies, homosexuals, etc.)

Hitler and the Nazis used Wagner's music as one of their most important manifestations of Aryan cultural accomplishment.

So, because of Wagner's character (and because of the way that his music was used by the Nazis) some other people, myself included, cannot, or will not, listen to Wagner.
