Cassette and vinyl sales are both up - but still represent a tiny fraction of music sales - vinyl
Is about 3% or 4% of sales in the UK.
As regards comparing consumption to sales: this is a fairly standard “equivalent” used in the music industry.
I’m unclear on what else you are saying. You say “so-called ‘streaming’” but why is it “so-called”? It’s pretty clear that the market has shifted to access over ownership or “so-called ‘streaming’”. Subscription streaming services are growing rapidly year-on-year. The stats are easy to find - perhaps the author didn’t feel it was necessary to quote numbers that are fairly widely discussed in mainstream and specialist media.
