EXTENSION REQUEST: Specific music to play when a particular game has been selected

It's an extension for Playnite that when you select a particular game, a background music plays, like in Playstation. You can also change the music for the game. (Ex. the music of your choice plays when you select GTA V and vice versa).

Can someone request this thing on Playnite's GitHub? It's because my browser keeps on getting "Your browser did something unexpected".

This extension is similar to this: https://www.youtube.com/watch?t=56s&v=UWHTI87IGuY&feature=youtu.be.
