Paradym shift.
When I first got a steamer which sounded as good as my other sources I typically did what I have done for the last fifty years… searched my memory for an album on the streaming service and play it. Ocationally it was not there… but often there were more albums by the same artist.
Over a relatively short time I switched from listening to the music I had already purchased (I own 4,000 albums)… to exploring new music.
Streaming has hundreds of times more music than I own or know about. Now I explore mostly… albums in the back of Stereophile, The Absolute Sound, recommended on Audiogon, Qobuz recommendations… new music added. I’ll check them out… new releases (many new high Rez releases of older jazz and classical as well as new new of every category. Occationally there will be an album I own that is not there… so what? (to me) I move on, if I listen to a dozen new albums a day I will still die long before catching up.
So, to me, with a different medium comes a whole different paradigm. Most of my life I was forced to listen to the same stuff over and over because purchase was the only way to fill my life with the music I like. My on-line library… must be 8K albums and growing daily. I probably listen to an old favorite of mine once a week.
