On it’s own, mppopmd
will happily sit in the background,
monitoring playback & keeping play counts & last-played timestamps
up-to-date. In order to rate a song, or indeed to do anything
with the information that’s being accumulated, the user will need to
induce their favorite MPD client to send the relevant commands
(see mppopmd Commands) to the mppopmd
commands channel
(see mppopmd Configuration), or fire-up something like
netcat
and start entering the commands manually.
Since neither of those options are likely to be convenient,
mpdpopm
ships with a small, purpose-built MPD client:
mppopm
(see mppopm Commands).
