I stream but my primary medium is CDs or CDs that have been burned to my NAS.
Currently I’m debating with myself about buying the Hyperion Romantic Piano Concerto 50 CD reissue. These are completely unknown or forgotten works. They were full priced CDs now being issued for about $4 a disc. They generally were never available to stream because Hyperion didn’t do streaming. Now some of them are available, I’m not sure how many, since Hyperion got taken over by a major company, and I’ve enjoyed to few that I’ve streamed, but I suspect that once the box sells out it’s limited run then they will disappear from streaming services
