> By doing this, you supported the bands you liked, and supported experimentation by accidentally subsidizing a lot of bands which didn't turn out so great (at the very least, experimentation in cool album covers...)

This argument can be used to justify basically any business practice. It's a weak argument. Should I be forced to buy 10 inedible doughnuts to find one editable one in the name of allowing people to practice making doughnuts out of random things they find in their kitchen? Should I have to buy 5 cars before I find one that doesn't break after a a month in the name of supporting the auto industry?

Obviously, this is nonsense.
