Google Play Music files can be exported via Google Takeout. However, the resulting file structure in the archives is flattened (see below for details) from the original (notably, no Albums listed) and many, if not most, of the files have truncated names.

In order to bring back structure, this project will iterate through the tracks and rebuild the albums list, possibly renaming the files as desired. To do so, the files in Takeout/Google Play Music/Tracks will be read for clues to piece the files together.

Furthermore, a pattern may be supplied in the configuration file to rename files in a way that better convey a track's metadata.

⚠ This project is not ever intended to modify metadata. It is strictly to organize the tracks into separate directories based on album and artist(s) in the tracks' metadata.

⚠ Please ensure all your music is intact before deleting the original Takeout archive files!

When you extract the files from the archives, you will end up with a file structure like this:

Takeout/
├── archive_browser.html
└── Google Play Music
    ├── Playlists
    │   ├── Playlist A
    │   │   ├── Metadata.csv
    │   │   └── Tracks
    │   │       ├── Track1.csv
    │   │       └── Track2.csv
    │   ├── Shuffle
    │   │   ├── Metadata.csv
    │   │   └── Tracks
    │   │       ├── Track1.csv
    │   │       └── Track2.csv
    │   └── Thumbs Up
    │       ├── Track1.csv
    │       └── Track2.csv
    ├── Radio Stations
    │   ├── My Stations
    │   │   └── Station1.csv
    │   └── Recent Stations
    │       ├── Station1.csv
    │       └── Station2.csv
    └── Tracks
        ├── Track1.csv
        ├── Track2.csv
        ├── Track1.mp3
        └── Track2.mp3

In the configuration file, "format" dictates how a file will be renamed. This value is a Python pre-formatted string, to be used with str.format().

The following fields are available:

• artist: the primary artist(s) of the track
• album: the album in which this track belongs
• title: title of the track
• disc_num: disc number; goes from 1 * to disc_max
• disc_max: number of discs that belong to the album
• track_num: track number; goes from 1 * to track_max
• track_max: number of tracks on an album's disc containing the track

To use these fields, simply insert the field name anywhere you prefer and surround the field with curly braces, like so: {artist}.

* Unfortunately, these fields can be missing/stripped from Takeout. Disc numbers will be updated to the default of 1 if missing, but track numbers can't be changed. In both cases, you will be alerted of the missing numbers and can take action later. Make sure to check the logs for has missing to pin-down the troublesome files.

1. Configure config.json by copying the example and renaming it. You may use tildes (~) to represent your home directory. You can also change the file name format.
2. Optionally, configure corrections.json. This file has the structure of a dictionary with up to 3 keys ("Artist", "Album", "Title"), with each key having dictionaries that transform values from the key to the value. For example, if a track spells an artist in all caps and normally the artist isn't spelled all caps, you can put the all caps name under "Artist" and assign it the expected value.
3. Run python main.py.

This code is designed around the following:

• Python 3.7+
  • eyed3 for parsing the MP3 metadata
  • other requirements

config.json

• "format": a Python pre-formatted string; see Format Structure
• "takeout_dir": a string that represents the path to Takeout (must end in Takeout)
• "dest_dir": a string that represents the destination directory, where subdirectories Artists and Albums will reside

corrections.json (optional)

• "Artist"
• "Album"
• "Title"

⚠ These corrections do not take in account any other context, only their associated field. This means that when a value matches, it will be unconditionally substituted with its replacement.

For instance, if you put "abc": "ABC" under "Artist", an artist (or group artist) whose name contains abc will now be changed to ABC, even if abc is in the middle of the name.

If any of the fields are missing, they will be substituted with an empty dictionary within config.py, but will not be used in corrections.
