Frustrating, and inevitable. Which makes it even more frustrating.
Here is the economic truth of the situation: about 125 years ago the landscape of music changed when the first commercial recording was made. Recorded music started as a private good - that it to say it was excludable (you could choose not to sell it to someone) and rivalrous (two people could not own the same wax cylinder.) The creation of a new private good was a business opportunity - a way to make profit - so business moved in and started profiting from this opportunity - profiting from the public it sold the recordings to, profiting from musicians by keeping the lion's share for itself and so on. As coalport noted recently (I think on levnet. I forget.) money is responsible for a lot of things in music - I suspect he was largely referring to the time prior to this, when royal patronage largely funded the development of classical music - but during the era of recordings as a private good it led to the pop charts and the mass marketing of music, and a few people - mostly business men, but also a few musicians - made a lot of money from selling recordings.
And then in 1981 the first commercial CD was produced. Another marvellous business opportunity - cheaper and easier to produce than vinyl, and better quality too (arguably) - so they strong-armed CDs onto the market. But in doing so they laid the seeds of their own demise by selling recordings in a form which could be copied perfectly and exactly. Not apparently a problem at the time, but time, tide and technology wait for no man, and pretty soon after a large percentage of the population owned the technology to copy CDs. And then the Internet came along and the means of freely distributing these perfect copies was available to everyone.
What was once a private good became a public good - non-excludable and non-rivalrous, and non-profitable. Currently sales are buoyed up by a legal fiction - that music recordings are still a private good, and by ethical considerations by the music buying public. In a contest between ethics and the law on one side, and the economic imperative on the other, the vast majority of people will glance briefly at their moral compass, check behind them for a policeman and then stare glumly into their wallet and follow the economic imperative. :-(
The music business is fully aware of this: what is The X-Factor and its ilk other than an increasingly desperate clutching at straws by a drowning business?
In the long term I think these hundred and so years will be seen as a brief historical blip - a business golden era when there was money to be made from recorded music. It's rather sad to be here at the end of it. True that a great deal of terrible music was made on the back of it, but some good stuff too. Let's not forget that.
I suspect that we will return to a pre-recorded music situation, where patronage by the super-rich (not royalty any more, money has largely gone elsewhere these days) will fund exclusive, high-brow music, and the common folk will entertain themselves as they always did...
