files saved on my nas, reachable via wired and wifi at home, played by via rasp pi players (recent i2s sound cards are pretty good).
one thing that I am glad I did; there was a short time I was listening to streaming music that I discovered via the old logitech slimserver stuff. I found some nice background music that was low key and worth having for various reasons.
I found a ripper - 'streamrip' - and it would sit there on a network stream (of the right type) and pretty well id the songs and name them as separate .mp3 files in a folder you pointed it to. let it run for days or weeks and come back to scoop up all the files. you then find so many dupes, too! but that's also kind of funny - you see what they 'played' lots of.
the best part of the CSB is: since I saved them, I have them. weeks worth. I would not notice if such a long playlist repeated a song. and you guessed it, the 'station' went off the air and now its gone, gone for good, most likely.
I have thousands of songs from that 'station' and its great bg 'working' music. if I had simply trusted the cloud, I'd have nothing now. instead, I grabbed mirror copies and I'm in good shape.
its also why I run youtube-dl to view YT videos. if its worth watching, I will save a local copy and watch from that.
