Make each Song/Dance have its own buff icon/colour
Description
Currently, Songs and Dances have one unique icon each. Ideally it'd be nice for each Song and Dance to have their own icon, which can be a unique icon, taking each song's skill icon as a base, or at least a different colour for each, to make them easy to identify. For instance, Poem of Bragi could be a blue colour, Assassin Cross of Sunset could be red, and so on.
Rationale
Simple QoL improvement, easier to see which buffs are up.
