> [regarding spotify] At the end, I had nothing to show for it. My carefully curated “library” was not mine

Not just your library, but your listen history and your playlists. I was very annoyed that I had to pay a 3rd party company to export this data so that I could import it into listenbrainz and navidrome.

Not to mention there's a song that Spotify removed from my "Liked" playlist that to this day I can't quite remember, though I can remember just enough of it to drive me mad: https://www.reddit.com/r/tipofmytongue/comments/1hklstg/tomt...

Anyway, I manage a homelab (read: a scrapbox ubuntu machine with 64TB of spinning disk attached) with 25,000 songs in it, and upon exiting my last position, spent my therapist-mandated "burnout recovery time" finally using `beet` to organize the damn thing. I still don't really understand beet, but now I have a semi-decent flow for abandoning Tidal: Find new released music on Listenbrainz, download it in Nicotine (filtering for >320). Idly browse a given user's other folders shared in Nicotine while waiting for downloads to see if they have anything else I want. Once done, `beet import /mnt/media/downloads/music2`, go through its flow, add anything to musicbrainz that isn't already in there, wipe the download directory when finished to clear out any cruft, and happily play it on Feishin on desktop (connected to my Navidrome instance).

I'm still sorting the mobile version of this out a bit. "Tempus" on F-droid seems the best Subsonic client, however unfortunately "offlining" music on it doesn't expose those files to the Android system or other apps, so I can only play those files within Tempus itself. That's not such a big deal when I've got my IEMs plugged directly into the headphone jack on my phone (yeah that's right I found a phone in 2026 with a headphone jack: sony xperia), but when I have my usb DAC plugged in, I want to use "USB Audio Player PRO" to bypass the android audio stack, and that can only play audio files it can find in local directories, no subsonic compatibility (but it does have a Tidal integration...). So lately I've tried just downloading playlists and albums from the Navidrome web interface on my phone.
