When I was in 12th grade, my parents spoke with my Rebbe about the fact that I enjoy non-Jewish music. His response was, “When we were his age, we listened to the Beatles and Simon & Garfunkel, so why is he any different?”
Just to note, my 12th grade Rebbe’s family was very close to my mother’s family. They lived on the same block, and both families knew each other well, so he knew what music they listened to.
