Just FYI, Apple Music supports automatic iCloud syncing of your personal music files that you drag into your library. Most of what I listen to is on streaming, but I can have non-streaming music, bootlegs, vinyl rips, Bandcamp purchases, and music only available on SoundCloud or YouTube (via yt-dlp) seamlessly alongside the streaming stuff.
I’ve tried to explain how limiting any other streaming service is to friends, but I’ve mostly been met with blank stares at the mere concept of wanting to listen to off-streaming music or even where one would come across actual music files these days.
