i agree with the OP about non-jewish music in jewish places. the jews in mitzrayim were also living among the goyim for a long time, but i guarantee you the music in their stores would have only been jewish.
yes, there are some non-jewish songs that are nice and are pretty. but thats not the point. the point is that when you’re listening to their music, you have to in some way appreciate the singer and/or composer for producing such an awesome song. you think, “well this singer can’t be so bad, look their songs are so nice so clean. theyre cool.”
were not supposed to think goyim are cool. we’re supposed to think rebbeim are cool. and that’s why we listen to music that’s composed and sung by frum Jews, music can actually help get us closer to Hashem, vs listening stuff that we justify to ourselves by saying “well, it’s not actually BAD for me…”
