sofdavar-
Well perhaps you associate the music with elements of society you do not wish to be connected to, and that makes you feel like there’s tumah in the songs.
Again, in the halachic sources relied upon by all major poskim – that is, in shas with the rishonim and the SA, the concept does not exist. This makes me very skeptical of your claim that there is something evil inherent in the music composed by a bad person.
