Blissify is an MPD plugin for bliss.
You can use it to make playlists of songs that sound alike from an MPD library.
Use cargo install blissify
to install it.
Then analyze your MPD library by using blissify --update /path/to/mpd/root
(or blissify --rescan /path/to/mpd/root
).
Then, when a song is playing, run blissify --playlist 100
to make a playlist
of 100 songs similar to the current song.
