# on many unix platforms (including Mac OS X) the following should do the trick

• Usage:

$ playlistbuilder --help
Builds a MPD playlist based on similar artists.
Every parameter is an artist.
If no artist is given, MPD is queued for the current track.
For more infos: $ view /usr/local/bin/playlistbuilder
    -s, --silent                     Don't write status messages
    -n, --no-mpd                     Don't interact with MPD
    -p, --pretend                    Just pretend every acton
    -d, --allow-duplicates           Don't check current playlist to avoied  duplicates
    -o, --only-similar               Don't allow tracks by the given artists themselves
    -t, --tags                       Treat parameters as tags instead of artists
    -m, --match MATCH                Percental limit of what a 'similar' artist is
                                     Detault 90
    -i, --items ITEMS                Max items to enqueue
                                     Detault all
    -e, --exclude REGEX              Regular expression to exclude specific artists

Get the artist of the current song, look up some similar artists, search your mpd-music for these artists and add all songs of them to the playlist

 $ playlistbuilder

Queue songs from artists tagged as 'rock' or 'jazz'. The artists have to be tagged at least 60% as often as the one with the most tags

 $ playlistbuilder -m 60 --tags rock jazz

Look up your music for artists similar to the Arctic Monkeys and the Kaiser Chiefs and add 5 similar songs randomly

 $ playlistbuilder --items 5 "arctic monkeys" "kaiser chiefs"   # you may also use -i

Use the -p (--pretend) switch to do all but the actual appending. Use the -m (--match) to give an other match-level (default 90, lower means the artist is less similar but you may got more matches within your music). Use -s (--silent) to supress non-error output. With -n (--no-mpd) you can disable the MPD-interaction and only see the list of similar artists. You can exclude artists via -e (--exclude). This can be handy if one artist is a substring of an other.

 $ playlistbuilder -p -e fatboy atb

playlistbuilder uses the same env-vars as mpc, so you can use MPD_HOST and MPD_PORT to configure the connection.
