Hi,
Thank you very much for the amazing tool!

It would be great to have an option on the cli to set the order in which players should be considered. One way to do so would be to add a flag when listing the players. For example

playerctl -p spotify,ANY next

would trigger the next action on spotify (if found). Otherwise, it tries with any other player.
Internally, I guess this could be done by sorting and then push the selected players to the top of the list in the order they appear in the CLI.
