This is why I used Spotify listeners and not plays or ticket sales or album sales. It’s a metric that doesn’t really require a band to be currently active. New hits will clearly improve the metric but we’re talking here specifically about a person’s outreach today and influence on a voting population.
The idea that more individual people listened to her music than had a single Beatles song in their playlist or a single Michael Jackson song in their playlist is pretty insane. I know I listen to at least one Beatles song a month, it doesn’t matter if it is new.
The big issue is that physical media degrades. A cassette tape wont sound the same as it did after just existing for 20 years. CD’s and Vinyl records if kept really well can last for 100 years or so but are delicate in other ways and a bad record player can cause permanent damage.
Preserving the experiences of others, art, media is important, but at the end of the day nothing we do is permanent. I know that thanks to online archives I can go and find old music if I need to. I am glad some folks preserve hard copies but a preserved collection isn’t really a functional one and a functional one isn’t really going to last 50 or 60 years at the same quality as what you can get from streaming.
