I view this in completely different terms.  Before file sharing existed, people would record songs off the radio onto their tape cassettes.  The music was already technically (but not legally) out in the public domain for anyone to hear, you were just bypassing the business model of ad supported revenue.  The music was even being beamed at you via radio waves against your own will, yet there's probably plenty of obscure laws trying to govern whether you can or can't record it and what you can do with it.

We have a similar situation with ad blockers on websites.  Their business model is starting to fail.  To me, the whole situation with music is just the state trying to prop up an invalid business model.  In the old days, entertainers were considered to have the lowest of social status possible.  This is one of the initial reasons Nero was ridiculed as an emperor, because he wanted to be an actor and emperor at the same time.  Even if entertainer's social status was garbage, they could still get paid doing it, they just had to do it through live performance.  There was no "record thyself and make millions".
 
Modern civilization elevates these entertainers from the social status of garbage men, to basically higher than the president of the country in both fame and wealth.  This is not to say they shouldn't get paid, but past history and current technology both point to the idea that they will likely be required to do so only through live performance.  If you're saying it's the government's job to make sure their invalid business model is still able to make them mega-millionaires without even having to do live performance at all, then that would be an extreme left wing view.
