That's fine until, for example and by analogy, you go to the store to buy beer, and you don't particularly care for IPA, but IPAs have crowded out half the beers that used to be there including the one you used to sit back and enjoy.

How does the analogy work with music though? Are you saying that because there is now over-produced pop there is now less rock, jazz or whatever you prefer? If so, is that actually true and verifiable by numbers?

That is still fine. There should be no expectation that what you want will always be available in the market.
