ynm melly

My boyfriend listens to that “murder on my mind” song by ynm melly and i constantly tell him i don’t like that he’s supporting a murderer by listening to his music (especially a song where he describes killing someone) and he acts like i’m being annoying about telling him to stop. am i in the wrong or is he? he doesn’t care that melly murdered 2 people bc he says its a good song. am i just over reacting?
