Solution: Make the music free of charge from the very beginning.
At worst,
treat it like the advertising it is--the more of it that gets spread around, the more fans, publicity, etc. you gain. Charge for merchandise, concessions, and ticket sales, which is where the real money is anyway.
Meh. IMO, Tangible goods and intangible intellectual property don't compare well. Apples to oranges.
More like apples to apple pie recipes.
Now that the internet, the greatest method of sharing and transferring ideas ever invented in the history of the world, exists, intellectual property as it once was cannot be valued in the same way. Magazine sales are dying. Newspaper sales are dying. CD sales are dying. Encyclopedia sales are dying. Even television is dying. Various other book sales, too--everything from recipes to religious writings to government publications can be found online. People are listening to the radio less and less, and it's all because it can be accessed via a means where everyone can share everything intangible,
for free.It's a bleak point, but the only thing to really be gained anymore is a feeling of satisfaction that you've helped humanity in some way, since you sure aren't going to get rich off of it.
