Is there a music thing that handles single tracks (lemmy.ml)

I've had this concept in my head for a while, I'm kind of amazed it doesn't exist yet.

I want to send a link to a music track to an app on my server, probably yt, maybe Spotify, and have that track be archived on my server, with the metadata from the service, preferably in a place Jellyfin can get at it.

There's a few ways to do that with YT playlist links, but not with adhoc requests for individual tracks, as far as I can see.

Is this not something that exists? I'm thinking it might not be too hard to write, if it doesn't.

opus can’t be tagged

I'm pretty sure that it supports tagging.

goes to try it out

$ yt-dlp -x https://www.youtube.com/shorts/syF8M3aeiWs >/dev/null
$ opustags beep\ sound\ effect\ \[syF8M3aeiWs\].opus |grep -v ^METADATA
language=eng
encoder=Lavf61.7.100
title=beep sound effect
date=20230316
purl=https://www.youtube.com/watch?v=syF8M3aeiWs
synopsis=beep

If you mean that this MusicBrainz Picard thing doesn't support tagging Opus, it sounds like it does:

https://community.metabrainz.org/t/musicbrainz-picard-doesnt-support-opus-files/467209

I have been having trouble tagging .opus files. Every time I try to edit .opus files I get:

(error: read b'\x1aE\xdf\xa3', expected b'OggS', at 0x0)

Looks like this is not a valid Ogg Opus file. Opus is just an audio codec, not a file format. Files with the file extension .opus are supposed to be inside an Ogg container, and that’s what Picard supports.

Your’s seems to be a Matroska file, and Picard does not support Matroska files yet.

And looking at the output of yt-dlp -x, it looks like it's Opus in an Ogg container:

$ file beep\ sound\ effect\ \[syF8M3aeiWs\].opus
beep sound effect [syF8M3aeiWs].opus: Ogg data, Opus audio, version 0.1, stereo, 48000 Hz (Input Sample Rate)
$

EDIT: Note that my ~/.config/yt-dlp/config file is:

--embed-subs
--write-auto-subs
--embed-metadata
--embed-chapters
--embed-thumbnail
--sponsorblock-mark=all

It may be that one needs --embed-metadata on the yt-dlp command-line if one isn't setting it in their yt-dlp config file to get the above tags; it might be that none normally get set.

Awesome! I just learned something today. Thanks for pointing it out so detailed!

If I want to just download the audio, I use eg:

yt-dlp -f 251 -o '%(title)s [%(id)s] f%(format_id)s.ogg' https://www.youtube.com/watch/?v%5C=fuHrtqx52J4
