Acknowledgments

This project is heavily relying on, on the one hand Scholnicks' itunesLibrary (itself a port of Drew Stephen's Mac-iTunes-Library), on the other hand on KristoforMaynard's music-tag.

Usecases

This project originates from the following needs:

1. Transfering playlists from different audio devices.
2. Convert cover artwork of songs to non-prog images.
3. Explore inconsistencies in a music library (incomplete albums, songs placed in the wrong location, etc).
4. These would be possible for both an iTunes or Apple Music managed library and a library managed by hand in folders.
5. Use playlists and existing cover artworks to create MiniDisc labels.

How to install

Through pip

python3 -m pip install audio-libraries-tlk

Warnings

In general:

• You are using this script at your own risks. Make sure you try the script on a duplicated small sample of your library to verify that it is achieving what you want.

In particular:

• Running the playlists components of the script should be safe as these don't imply modifying your music library but just extract some playlists and create new ones.

• Running the cover artwork options is much more risky as the script will potentially modify the cover artworks inside your music files. If your music files are not properly splited by album (two songs of different albums are present in the same folder) then you the cover artworks of the two albums will be mixed (one will replace the other). In other word, the script assumes that songs in the same location belong to the same album. In case of doubt, you can start by running the script with all the cover artwork options set as False (the default case) and with the option --create_special_playlists==True. This will produce a csv file showing all the locations containing songs of multiple albums.

• Again try the script on a small duplicated sample of your music files and check if the reasult pleases you.

Be patient

Depending on the option you choose the script can take a long time to run: up to ~1 hour for 1 30k songs library on a mac mini M2.

To save time in the case you need to run the script twice and to avoide the full scan of the music files or of the .xml file twice, a .pickle and a .csv file are created by the first scan of the library. These will be reused in the the second call to significantly reduce the time of the second call.

However, if your music files or .xml have changed between the fiorst and the second call, you need to remove the existing .pickles and .csv are these wont reflect anymore the state of your music library.

Outputs

The .m3u8, .csv and .picklefiles created by the script will be located inside the PATH_TO_LIBRARY_DATA.

How to run

1. For general Library Scan and cover Artwork update

• To run the script from an iTunes or Apple Music, first go to setting/Library/Export Library. Save the .xml file in a folder and copy this path (for instance /Users/user_name/Music/ where you have placed the file My_Library.xml).
• To run the script from a music library that is simply organised in folders (for instance Artist/Album). Simply copy the path pointing to our music directory (for instance /Users/user_name/Music/Music/Media/Music).

Then, for instance, to extract all the playlists contained in your music library, convert them into a format readable by a new audio device, and create a cover.jpg file for inside each album folder, run the command:

python3 -m audio-libs-tlk --path_to_library_data='/Users/user_name/Music/' --orginal_path_written_in_playlists='/Users/user_name/Music/' --updated_path_written_in_playlists='/home/Music/' --create_cover_jpg=True

To save time on the second run

To save time in the case you need to run the script twice and to avoide the full scan of the music files or of the .xmlfile twice, a .pickle and a .csv file are created by the first scan of the library. These will be reused in the the second call to significantly reduce the time of the second call.

However, if your music files or .xml have changed between the fiorst and the second call, you need to remove the existing .pickles and .csv are these wont reflect anymore the state of your music library.

2. To create MiniDisc Labels

1. Create a playlist from an audio software containing the desired albums.
2. Save this playlist using .m3u8 format with a name that contains the word 'MiniDisc' (MiniDisc.m3u8for instance) under a path
3. Run the command:

python3 -m audio-libs-tlk --path_to_library_data='/Users/user_name/MD_PL_Location/' --create_minidisc_labels=True

4. Wait for the script to run (on a Mac mini M2 it takes less than 15 seconds for 10 albums) and review the .svg files created iniside /Users/user_name/MD_PL_Location/MiniDisc-Labels. It is very likely that some labels will not satisfy you. In particular, long Artist Name or Album Title will overfolw the labels.
5. To fix long Artist or Album names, open the csv file called 'your-playlist-name_albums.csv (for instance MiniDisc_album.csv). There you can modify (in particular shorten/abreviate) the values in the columns 'Display Album','Display Album Artist' (becarefull not to change the column 'Album','Album Artist' ).
6. You can also use custom text and background colors using any hexadecimal color cof your choice or one of the color (as a string) in the list below.
7. Run again the command:

python3 -m audio-libs-tlk --path_to_library_data='/Users/user_name/MD_PL_Location/' --create_minidisc_labels=True

8. Review the updated .svg files.

Available colors

'black','sky_blue','blue','blue_steel','blue_green',
'navy_blue','blue_turquoise','fushia','gold','green',
