Sorry for the delay, I'm busy with university stuff at the moment. I think I prefer a `begin()`/`end()` interface with a proxy over the single function with callback. Would you...

If you be willing to write something, I'm happy for a PR.

Sure, I'll implement it.

The API I've implemented is not available on Windows AFAIK; it's a Linux only protocol.

Anything I could do to help it get merged?

I've just pushed another fix for a bug when using `playerctl play-pause`.

I've changed it. Do you want me to clean up the commits and force push?

Volume change support is now implemented as well.

Can this be merged?

Just using wchar_t for the notion of thousands separator is still wrong. The type to represent a UTF character is string, as it can span arbitrary many code points.
