Comlink-X:
YOu insinuate that music is nothing more than notes and contains nothing of the composer and has little or no power.
Exhibit A: A large majority of Jews (who listen to classical music) who don’t listen to Wagner.
Exhibit B: The importance gedolim through the generations have attached to music, even ones nowadays.
Exhibit C: Music of the Leviim in the Beis Hamikdash which brought people to teshuva.
I know you will nitpick and find something in my answer which is not good enough for you but that is okay. You are free to live your life as you please ultimately, my opinion notwithstanding. If you want to listen to whatever music you want go ahead but though you will deny it the music you listen to will have an effect on you.
