Give Baron and Vilemaw their own theme?

With the new map facelift why not a musical facelift too?Giving Baron a creepy slow paced theme (think lower brimstar from metroid) around his river area after let's say,35 minutes,would make late game baron dances seem more intense and exciting.Hitting or fighting around Baron area would make the music jump to a fast pace until there is no fighting for about 20 seconds or you leave Baron area.When Baron is dead music would be normal and a couple seconds before he spawns he'd roar and the slow theme starts again if you're around his river.How awesome would this be? It would also make esport Baron dances seem even cooler.
