The previous version of the configuration was complaining that my ‘config’
section was not a valid value for the ‘package’ section. I didn't quite
understand why it would complain about that, so I decided to use my now improved
Guix Home knowledge (compared to when I copied the previous version) to just
rewrite the service in a way that matches my other services.
This also includes an attempt at installing a custom SCSH that defines some
search paths. But unfortunately it didn't work, so the SCSH ends up being the
usual one and the ‘mpd-random-albums’ package doesn't actually work.
The main MPD configuration does work, though.
This also includes the instruction to install tmsu which I want to try out
again.
