You would love Lucio from Overwatch. His entire kit is built around dynamic music and how you're playing the game at any given moment. He acts as the center of a large aura that either gives a passive speed increase or a passive healing stream. You can cross fade between the two tracks whenever you want with no limitation giving you a choice later on whether to amplify one or the other. You can even cross fade while you're amplifying.

The character's ultimate is just a bass drop that animation locks you into slamming the ground. I didn't even mention that you're a sci-fi roller blading support that can wall ride around the map. You can bass drop off the walls or just whatever high place you can. Nobody gets mad at you for looking cool as fuck.

The music is sick definitely take a listen!
