companion: dj and groove states in Mood

A DJ burst ranks just below the headphones sing, so both arriving together
sings first. Music turns only the first idle stage into a groove: yawning
and lying down still win, so music does not keep her awake and the
screensaver handoff is unchanged. The groove pick is an input, keeping
pick() pure.
