Emulation Dolphin Custom Music

[TheJoGamerHD]

Hello,
I am making an Wii Sports texture pack wonder if I could change the music so it would be funnier
I was looking for tutorials on the Internet but only for Mario Kart Wii and I thought maybe it would also work for Wii Sports, I extracted my dumped ISO and the Sounds folder that was in the video is not in my Folder and I thought Ok it only work in Mario Kart

Any Help would "help" hoppfully

Regards
