“my OPINION is that these songs do not belong at any Jewish wedding, not only at mine, take it or leave it, as i said somewhere before!”
Ok, fine, don’t have it at your wedding, and do not feel it is right for someone else to have at someone else’s wedding, but for goodness sakes, please do not tell the other person that their choice to do so is a bad thing. Keep it to yourself, because your opinion (while worthy) is not halachic in nature.
At my own wedding, I did not allow ANY non-Jewish music to be played even during the dinner. All dinner music was slow Jewish music. But I did not presume to tell my friend (a VERY frum woman) who marched down at her own wedding to some symphony piece, that she offended my sensibilities by doing so at a chasunah.
The entire argument here comes down to whether or not it is always appropriate and obligatory to give mussar to someone. The answer is ONLY when the person is clearly violating an absolute halacha, not a chumrah, not a minhag of some, etc. If a frum yid is eating kosher cholov stam ice cream and you feel that it is an aveira to eat anything but cholov Yisroel, please hold your tongue. If you see him eating it right after he ate a salami sandwich, by all means remind him he is fleishig.
