I don’t think all Jewish music comes from the goyim. You can feel when a song has that goyish sound/feel to it- or when it touches the soul, and most definitely is not from the radio or broadway etc…
I was once told that when listening to music, the composer’s intentions and feelings seep through. That’s the reasoning behind not using goyish tunes
But this is a huge yetzer hara for me, so I can’t darshin. I enjoy all music. Be it Yanni, Gershon Veroba, Isaac Honig, Yonason Schvartz, Schwekey, MBD, Chaim Yisroel……………..
