The headline says "More people bought physical CDs and vinyl than songs on iTunes" but the numbers given are "total download sales in 2018 [were] a little more than $1 billion", "Purchases of full album downloads likewise fell, by 25%", and finally "Sales of physical media... totaled $1.15 billion".
So are we talking about number of people, as said in the headline, or song sales, or album sales, or money?
I clicked through to the report and the most shocking thing to me was that people spent $25 million on ringtones and ringbacks in 2018.
As far as I can tell, the numbers don't account for any second-hand sales of physical media at all, which may not be a thriving market but also isn't trivial, at least in terms of unit sales. Money-wise, it's probably pretty low, due to high supply and low demand resulting in low prices.
Regardless of what they counted or how, I'm pretty sure most artists are still getting fucked.
