What makes something a musical instrument? Shouldn't speakers be considered an instrument?
I didn't mean to preclude recored music in that post. To the point, it's not as unanimous as you make it out to be since R Ovadia was matir as well as others that I've heard מפי השמועה, but I didn't want to bring it up since it comes down to individual Rabbanim and how they pasken - and how you think the 'Oilam' is noheg which is subjective and unprovable.
I only walked into the conversation when somebody made the ridiculous claim human singing is Assur and one needs a Raya to be matir, when it's a mefurash Shulchan Aruch to differentiate.
There can interesting scenarios in the middle to think about, like a robot playing actual musical instruments from prerecorded notes which may not be as fluid and spontaneously responsive as a human, but then AI can do a lot of that as well. Then you can argue an element of the Simcha is created by the person playing it aside from the actual sounds produced. etc etc.
Ultimately, live music is a multi billion industry because it's different than recorded somehow.
