Comment 1 for bug 714750

In the specification I also said: "However, the API should provide a way for a player to register a Play action, so that the Play button can work even when the player is not running."

I suggest that Banshee use that API, so that if it is not running, pressing the keyboard's Play button (or clicking the Play button in the sound menu) will launch Banshee and continue playback from where it left off.
