I'm going to be a wet blanket here. I love music. I spent my tesn and college years spending so much money on vinyl that the used record guy used to give me his roll of cash to tend to the store while he took a leak.
I have almost a full year's worth of listening on my drives at home. But, entertainment is a want, not a need. I hardly listen to my music anymore, much less the pablum that passes for popular music now. My entertainment budget, as paltry as it is, is spent on travel or meals and drinks with friends.
I love music, but I don't value it as much as I do travel or being with friends. I'm not willing to shell out even one dollar for a concert ticket or even an mp3 stream. I still toss money into the musician's jar if I'm at a venue where music is being played live or even on the street if the busker seems authentic to me.
But, like teachers, the reason that it's difficult to get paid for certain forms of work is simply that society doesn't value that form of work. Athletes get paid because people love beer and expensive new cars. Some entertainers also get paid, but usually the ones spending the money are either those who didn't have tto work for it (kids) or people who haven't discovered other ways to spend their money.
I'm not saying that it's fair or just or whatever, but that's the way it is.
