feif un- I will try to look up the teshuvah from R’Moishe zz’l.
Actually, you have just introduced a new “gezeirah” : “No fast music because POSSIBLY you may end up dancing”? Since when do we make up our own gezeiros? Especially concerning a distant chumro…
I have great problems with the various “additions” that we continually make, especially concerning aveilus and ” al kamo vekamo” for sefira that is a “minhag hageonim’ and is never mentioned in gemoro.
to kapusta- I have no quarrel with anyone who wants to impose upon himself certain chumros. I do have problems when you try to impose it upon the whole world.
