RUN THIS AT YOUR OWN RISK! MAKE A BACKUP BEFORE RUNNING THIS!

apit allows batch tagging .mp3 and .m4a (AAC and ALAC) file metadata tags using data from Apple Music/iTunes Store.

At least Python 3.10

$ cd apit-source-code/  # i.e. this folder
$ pip install .

$ apit -h

$ apit list ~/Music/Music/Media/Artist/Album/

Example using an url:

$ apit tag ~/Music/Music/Media/Artist/Album/ https://music.apple.com/us/album/album-name/123456789

Example using an already downloaded metadata file:

$ apit tag ~/Music/Music/Media/Artist/Album/ ~/Desktop/Artist-Album-123456789.json

The filename of your files must have the following format in order to match them against the Apple Music/iTunes Store metadata:

1. optional: disc number (followed by "-" or ".")
2. required: track number (followed by an optional ".")
3. required: .mp3 or .m4a extension

Examples:

• without disc number (defaults to disc 1)
  • 14.m4a, 14 title.mp3, 14. title.m4a, #14.m4a, #14 title.m4a
  • 2. 14 title.m4a (track 2: title contains the number 14)
• with disc number (e.g. disc 2)
  • 2-14 title.m4a, 2.14 title.mp3, 2.14. title.m4a

You must provide a source for the metadata to be used. Simply search for the album matching your files in the Apple Music/iTunes Store functionality or in a search engine and copy & paste the url to that album. The format of that url must match the following form (as of 2020-05 using Apple Music on macOS 10.15 Catalina):

https://music.apple.com/{COUNTRY_CODE}/album/album-name/{ID}
e.g. https://music.apple.com/us/album/album-name/123456789

or the old style iTunes format:

http://itunes.apple.com/{COUNTRY_CODE}/album/album-name/id{ID}
e.g. http://itunes.apple.com/us/album/album-name/id123456789

Even this format will match:

http://x/us/x/9/123456789?i=09876

This will look up the metadata of the album with the ID 123456789 in the US store of Apple Music/iTunes.

You should compare your files against the album's metadata you found via the iTunes Store or a search engine. Sometimes the songs' track order vary from album edition to album edition (e.g. deluxe edition) or the album published in another country has a different order. This means that your files will be tagged using the wrong metadata if you choose the wrong edition! You can overcome this by renaming your files before tagging to match against the appropriate metadata. Optionally, you can edit your files' track number metadata again after tagging to revert to your original track order.

By default, artwork from Apple Music/iTunes Store is saved to your files. Additionally, you can specify your desired pixel size (default: 600).

Examples:

$ apit tag ~/Music/Music/Media/Artist/Album/ https://music.apple.com/us/album/album-name/123456789
$ apit tag --artwork-size 1000 ~/Music/Music/Media/Artist/Album/ https://music.apple.com/us/album/album-name/123456789

You can create backup files before updating metadata if you put --backup (short: -b) in your command.

$ apit tag --backup ~/Music/Music/Media/Artist/Album/

To see more information what happens you can put -v into your command. Using -vv enables debug output.

$ apit tag -v ~/Music/Music/Media/Artist/Album/

Install apit in an editable mode:

$ pip install --editable ".[dev]"

This will install tox and other development tools. Tox is used to run for example tests in an isolated environment. Show all possible actions using:

$ tox -a

Running a specific tox command will install its necessary dependencies in separate virtualenvs.

Code style is ensured using a pre-commit hook:

$ pre-commit install

$ tox -e build
