I've recently "dusted off" my digital #music library that I built up over 15+ years (mostly from iTunes and Amazon Music, plus my long-ago-ripped CD library) before music streaming became the norm and it's been a whole lot fun re-discovering tracks I'd forgot about, actually buying new music (thanks #Qobuz & #Bandcamp for DRM-free lossless #FLAC audio files at reasonable prices).
I discovered the #OpenSubSonic and #Navidrome ecosystems, and now I can stream my *owned* music library from my phone, transcoded dynamically to Opus (the audio format, not the LLM model) which is like the modern and better MP3 format.
If you're looking to escape the big cloud streaming subscription ecosystems and have some tech savviness, definitely check it out.
