Star Guardian Skin Music

I think it would be neat to have Star Guardian music option that players can enable, kind of like the thing DJ Sona has. If someone has a Star Guardian skin (Lux, Jinx, Poppy, Janna, Lulu, or Poppy), they can either use the music under the sound tab or hit O and click a button next to the person with a Star Guardian skin. Whenever I go into game with Janna or Jinx (the champions I have the skin on), I hear the music for only 1 minute and I'm disappointed that I can't play the whole game like that.
