So why does so much amazing music continue to get made, daily, as opposed to amazing journalistic content? Writing and producing music is no less challenging and time-consuming.
While not universal (e.g. newsletters on certain specialized topics), journalism has historically been associated with news organizations whereas music/art/etc. has been more associated with individuals or small groups. (Though certainly producers have played roles.)
I’m not sure if it’s true that there’s less amazing written content than music content - I wouldn’t even know how to measure that.
