Oh definitely. I don't think people know how much work goes into the typical pop song, even though it may sound like anyone could write and record it.

People think they could sing Britney Spears just like her until they get behind a mic to record. Most people don't even know the cringey feeling of "God, I didn't know my voice sounded like that" after having heard their own recorded voice for the first time. Or how out of tune and rhythm they actually are.

So no. Everybody thinks they could sing the typical pop song, but I doubt that they could.

It's not that pop singers aren't talented. It's just that pop music as a genre is pretty much boring, and the artists that appear every season, or every "America's got talent" edition, they all are easily forgettable. You could switch covers and sell Selena Gomez album as Ariana Grande album and noone would even notice the difference.

Pop music is a commodity, and as any commodity it's pricing/value is basically a race to bottom.

That’s not the point GP made. Selena Gomez and Ariana Grande have roughly similar genres but Ariana is a musical titan who can famously sing in any style she chooses.

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.
