Module bliss_audio::distance

Module containing various distance metric functions.

All of these functions are intended to be used with the custom_distance method, or with playlist_from_songs_custom_distance.

They will yield different styles of playlists, so don’t hesitate to experiment with them if the default (euclidean distance for now) doesn’t suit you.
