Yes... I'm sure they realistically would mind....
I'm just making a bit of light of the situation, and find the idea that fear of "the man" (who perhaps is working diligently for the due rights of the artist) could result in a future bar landscape where live/recorded music becomes essentially "underground".
I grew up in an era, right or wrong, where live music was on stage most nights, typically poorly done covers, and likely with little compensation to the original artist, and when said live music wasn't on, there was always a juke box, or sometimes just the bar staff playing CD's from their personal collections.
If they had a tv they also probably had Monday Night Football playing, even without express written permission from the NFL lol
Maybe that era was in the wrong, maybe artists got screwed, but it was pretty much the post work/weekend entertainment for a lot peoples youth, and there music which essentially provided the "soundtrack" for it. Its an odd thought to think that some venues might start doing away with live music, juke boxes etc, if they don't want to "pay to play" so to speak.
I'm talking half-joking here, but at the same time, its a real question of how things are going to look moving forward ?
