NA Sounds and Korean Sounds

I am currently watching a lot of Korean players to see what they are doing differently that makes them so good and in the background of the Korean client in-game, I hear this peaceful music and a peaceful announcer. In NA, the music is kind of fast-paced which kind of makes me feel stressed and the announcer sounds like he has a sore throat an decided to scare kiddies (not saying it doesn't sound cool). Maybe Rito can make an option where you can change what kind of sounds there and the the voice of the announcer. Thoughts on this?
