Isn't the same thing achievable with the "mpc idle" feature, which
allows you to listen for events from mpd ?

Like your other package, I'd prefer to have some evidence of even some
limited adoption/usage of a software package before adding it to
Buildroot.

Nonetheless, here is a review below.

Please avoid first person sentences. This strengthen the feeling of
"this is a personal project and nobody else but the original author is
using it".

Please add an empty line here, followed by the URL of the upstream
project homepage.

Please use the Github helper, and add a hash file.

We normally use /usr as the prefix, not /.

You can pass all those variables on the make command line, and
therefore use $(TARGET_CONFIGURE_OPTS) instead.

Thanks!
