sure, some pop artists have great skill, but that's beside the point. my point was that singing entertainment (e.g., pop) is widely available (someone sitting near you right now can probably sing well enough to be entertaining), so not scarce. you can find millions of decent takes on pop songs on youtube. and further, the level of passable entertainment is low, both because plenty of people can sing passably, and because enjoyment of the music comes not from admiring the skill but mostly from other factors.
