“that “it is not really hurting” me? “
Because if you are honest with yourself, you will see that it is the IDEA of that music being non-Jewish and played at a simcha, that is bothering you, and not the melody itself. For one second, try to just be a person listening to something beautiful or inspirational. Hashem gave chochma to people besides the Jews, and that chochma allowed them to produce beautiful music, great art, and literature. If there is something that personally offends you because it is not to your taste, so be it. Don’t listen to it on your own time, don’t read it, and don’t go to see it in a museum. But don’t make negative comments that imply that someone else is practically committing an AVEIRA because THEY happen to like it.
I don’t care for rap music OR heavy metal. But even Led Zepplin wrote a piece like Stairway to Heaven (the one thing I can listen to and not cringe). You can dislike something, but it doesn;t have to hurt you.
