I think you might be able to implement this with a Home Assistant automation or basically anything external that interfaces with one of the remote control APIs.

Or even with a very simple shell command like "(sleep 7200 && mpc toggle) &"
or
"echo "mpc toggle" | at now + 2 hours" in case atd is installed and running
