Spotifyd is a Spotify daemon, not an user application. It makes perfect sense to run as a service. Though personally I would run it as a user service instead of a system service.

If the company is reviewing people on that metric, every manager should be fired for grand incompetence. I rather wonder if the driver himself doesn’t have a side business where he picks up trash for cheaper/free for friends. And to correct the number of how much kilos of garbage he’s hauling, he notes a few customers as overflowed. That way the numbers add up again.
