[Feature Request] SPACE key to pause/play the current track

SPACE key is almost a well known and accepted key shortcut for toggling the play/pause status of the current track in many applications (e.g. Pandora, SoundCloud). I'd like to have the same keyboard shortcut to be implemented here. I just don't want to aim for that small play/pause icon every time I need to quickly pause/resume the track I'm listening to.
