and then You have the exactly opposite exemple :
the Dagger Records label owned by Experience Hendrix LCC releases "officials bootlegs" on physical formats
in this case, it exists on CD, it's "official" (not bootlegs) , but it's not part of the "official discography" so to say, because it's not real classical "albums"
I far prefer this than having concerts uploaded on YouTube channel...
and I fully agree about streaming not being eternal
I have all my music in physical fomats OR files downloaded and I listen to it on my Sony portable player
