Here we go again…
I submit to you that there is not a person alive today whose taste in music is not influenced by “Goyish music.” The idea that certain songs are inherently “Yiddishe nigunim” while others are “Tamei” is a myth. With the reputed exception of the Nigun used for Birchas Kohanim, all of our music for hundreds of years has been influenced by the people around us, sometimes directly and sometimes indirectly, but always to a great degree.
I certainly understand that a person may have his own taste in music, and consider certain tunes to be nothing more than noise. However, the fact that you feel this way doesn’t make it so. For people who like and enjoy it, (and, yes, find that it inspires them to Simcha and feelings of spirituality,) the tune of Meilech Kohn’s V’uhavtu is no less “Yiddish” than Ka Echsof.
