music-shuffler creates playlists based on the BPM of a track, and it also emphasizes artist variety.
I didn't like how the Apple music app shuffled music, and I wanted a playlist that had smoother transitions between tracks. When DJs mix music, they typically change the BPM up or down by 5% from the current track, so I used that as a rule of thumb for selecting the next track. The sorting algorithm will also try to add artists that haven't been added yet and will try not to play the same artist consecutively.
Run pip install -r requirements-dev.txt to install the project dependencies. You can test the build by running make test.
Run python music_shuffler/shuffler.py -h to bring up the help prompt.
Apple music unfortunately does not have BPM information for tracks, unless you tag it manually. Eventually, I'd like to have the input and output file generated in a format that is easily importable to my library.
