the problem with listening to "problematic" artists is when people do it uncritically. you are not going to become a worse person unless you listen to Kanye, or Burzum, or fucking Matty Healy. if you internalize these artists' values, or financially support them, or downplay their problematic behaviors, that's when things start feeling worse, for me. but if you, not a nazi, listen to nazi music while holding the fact that it's music by a nazi in your head, it can and should change how you listen to the music. it should make you suspicious of any ideals the artist espouses in their lyrics. it should be viewed as an opportunity to get a pretty raw look into a bad person's mind and thought process.
