[@Girlie1Bomba] Less of a command, more of a reminder/call-out. In your example, a player in OOC (not the character IC) could say something like "My chara plays a Vanilla Ice song cuz I know Girlie's character likes to dance!" ;D  She wouldn't HAVE to dance, but it's acknowledgment that the decision was made while thinking of your character instead of some freak accidental Vanilla Ice song.
