FreeDB, a Free CDDB, has closed, so I'm using MusicRepair with the Spotify API to automatically retrieve tags.

Hello, I am incompetent.
FreeDB, which I used to rely on quite a bit in the past, has shut down.
So, I found MusicRepair, which can automatically retrieve tags using the Spotify API, so I'll use it.

You can install it with pip.
pip3 install musicrepair
musicrepair
When you type that, on the first launch, it will complain, 'Give me the API key!'
Warning, you are missing the Spotify client ID. Add it using --config
Warning, you are missing the Spotify client secret. Add it using --config
Warning, you are missing the Genius key. Add it using --config
usage: musicrepair [-h] [-c] [-d REPAIR_DIRECTORY] [-R] [-r REVERT_DIRECTORY] [-n] [--format RENAME_FORMAT]

So, I'll go get the Spotify API.
I've always had a bad relationship with Spotify; just opening someone's playlist would cause a redirect loop, and this time too, the site was slow and I couldn't access it like this, so I probably won't use it in the future. Perhaps they're dedicating all their resources to the mobile API.

Honestly, the Redirect URI can be anything, but since it was a required field, I entered my site with a different domain. If it's just for API usage, I honestly think a fictitious one would be fine.
Then, check WebAPI and it will be issued, so just paste it into MusicRepair.
musicrepair --config
Enter Spotify client ID : the client key you obtained here
Enter Spotify client secret : ~secret key
And now, since it's asking for a Genius API key to get lyrics, I'll go get it.
Coincidentally, I had already gotten an API key a year ago for AI lyric translation, so I'll use that as is.

The name I gave to the API was too sloppy, which even made me laugh.
Enter Genius key : Enter Genius CLIENT ID
Now the setup is complete.
Since I want it to search recursively within the directory, I'll add the -R option.
musicrepair -d music_folder -R
This will automatically retrieve them.
Since I want it to run in the background even if the SSH session is disconnected,
if I try to rename additionally, it seems an error might occur if there are special characters, so I'll add an option not to rename.
nohup musicrepair -d music_folder -R -n &
I'll set it up like this.
That's all for now.
Looking forward to seeing you again.
