@Riot Take a note out of Smash Ultimate's Customisation [Music]
Now I've played Smash Ultimate for a while now and the one thing I think it does really well is give a lot of power to the player to do whatever they feel like doing, something that is reflected in their menu select screen. Now there are tons of things I enjoyed about this menu but for now lets simply focus on one small but amazing option. Customizable stage music.
I personally feel adding this option would be great for a game such as League of Legends as year after year the music team puts out absolutely amazing songs that we'll only get to enjoy for maybe a week on the login screen and then never again unless you go out of your way to look the song up again. So why not give players a choice during per example champ select or even better, as presets within their item menu in the collection so you can set music for each of your favorite champions.
Music has the power to set a mood and make someone feel even more invested in the moment or their champion.

I honestly think the game could honestly only benefit from adding a feature such as this.
