daasyochid: all sam2 said (in another thread) that the first mention of such an issur was (maybe) by the pri megodim ,who lived appx 200 years ago. And I accepted that the additional issur of LIVE music (concerts, simchas) may be acceptable. That alone is a big addition to the original takonoh. Now, you and others want to add ANY music to this takonoh- an exceptional chumrah that has no basis in the original takonoh.
I venture that even R’moshe zz;l does not find a basis for this in the original takonoh. As far as liquid soap, it was an illustration that one does not have to be bound by R’Moshe’s chumros because he says that liquid soap on sabbos iis ossur.
