I would love it if i had the option of starting spotify with arguments like spotify playlist-id where it auto plays the given playlist on start-up. And then some flags like -r for repeat or -p for starting paused. This would be useful if you had a i3 setup where a hotkey you could start spotify and your favorite playlist.
