Tbf, I think radio absolutely used to be better before iheart and their ilk bought fucking everything and turned every goddamn station into a hypersanitized prepackaged mix of the same 10 bloody songs over and over. Therefore, by extension, I could 100% see how someone basing their opinion on what actually gets radio play could easily arrive at the conclusion that music is worse now.
I’m guessing whatever it scraped to generate this was intended for divvying up food rather than doing actual math. 1/3 plus a third of a third is close enough to a half if you’re talking about portioning out pizza or leftovers or what have you.
