Vinyl or 8 track? Who remembers the Elcaset?
FWIW, I have AT&T gigabit fiber. So far, about 5 years, it has been remarkably reliable.
You can stream your files from a NAS to any streamer (in the local network) just fine when your ISP is completely dead and gone with the wind!
On the same note dude, if you like an album, buy the artist's hires digital album (put it on your nas) and pay the artist. These streaming services pay them peanuts. On a positive note, you will have permanent ownership of that album and will no longer be "renting" it from the streaming service.
@audioman58 I see several people have already answered your question. You need a streaming server that does not require an internet connection like Roon. My setup is simple, I only stream in one location, my dedicated music room. I use a Cambridge Audio CXN V2 to stream Qobuz. I also have a 1TB drive that is connected to the USB port on the back of my Streamer. If you are looking for whole house streaming, you will need a music server with Endpoints. As I stated earlier, there are tons of solutions mentioned in this post and defer to those since I only stream in one location. Hopefully you've gotten the info from here.
Enjoy the Music..
