playlists

My playlists under version control.

Requirements

• mpd (with your library imported)
• mpc
• python
• bash
• a list of your favorite tracks
• a list of artists linked to a playlist (see below)

Limitations:

• all the tracks of an artist are grouped and will be added to the same playlists
• mpc query language is quite limited and only support exact matches

MPD matching

Create a text file (for example files/00_favorites-tracks.txt) containing your favorite tracks (one by line, with the format ARTIST - TRACK):

ARTIST1 - FAVORITE_TRACK1
ARTIST1 - FAVORITE_TRACK2
ARTIST2 - FAVORITE_TRACK3
ARTIST3 - FAVORITE_TRACK4
...

I personnaly export all my favorite tracks on last.fm with this script.

Run the mplaylist.sh script:

./mplaylist.sh files/00_favorites-tracks.txt

Output:

• files/01_result-mplaylist.csv: tracks matched with mpc
• files/01_result-mplaylist-missing.csv: tracks not matched with mpc

Playlist creation

You will need three files:

• files/02_playlists.csv (fields: playlist_id;playlist_name):

1;Rock
2;Pop

• files/03_artists.csv (fields: playlist_id;artist_name):

1;ARTIST1
1;ARTIST3
2;ARTIST2
2;ARTIST1

Those two files says "ARTIST1 and ARTIST3 songs will be added to the playlist Rock, and ARTIST1 and ARTIST2 songs to the Pop playlist".

Adding artists in multiple playlists is supported, just duplicate the entries with a different playlist id.

• files/04_fix-missing-tracks.csv: manually add paths for the missing tracks in 01_result-mplaylist-missing.csv (fields: missing_track;path):

ARTIST1 - MISSING_TRACK1;PATH_TO_TRACK1
ARTIST2 - MISSING_TRACK2;PATH_TO_TRACK2
ARTIST2 - MISSING_TRACK3;PATH_TO_TRACK3
ARTIST3 - MISSING_TRACK4;PATH_TO_TRACK4

Run the create_playlists.py script (change the LOCAL_BASEPATH and BASEPATH global variable to your own):

python create_playlists.py

BASEPATH indicates what the mpd matched tracks will be prefixed with. It's used to complete the paths as mpd uses internal paths and not full paths.

LOCAL_BASEPATH indicates the base path to delete after checking the validity of the manually inserted paths in 04_fix-missing-tracks.csv. The BASEPATH will then be used as a prefix.

By setting BASEPATH to /music/ and LOCAL_BASEPATH to /home/user/nfs/Musique/, the script will delete /home/user/nfs/Musique/ from the paths found in 04_fix-missing-tracks.csv and will create playlists using /music/ as base path. If you want to use your playlists on the same filesystem configuration, you can set LOCAL_BASEPATH and BASEPATH to the same value.

Output:

• files/03_artists_NOT-FOUND.csv: artists not found in 03_artists.csv
• files/04_fix-missing-tracks_NOT-FOUND.csv: missing tracks not found in 04_fix-missing-tracks.csv

If those files are empty you're good, otherwise just add entries in 03_artists.csv or 04_fix-missing-tracks.csv and restart the script create_playlists.py.

Exported playlists will be in the playlists folder.

Import

I automatically import those playlists into airsonic (airsonic can watch and import playlists from a folder).

My music folder is mounted under the /music/ folder in my airsonic container (hence the /music/ prefix in create_playlists.py).
