It's my favorite soundtrack when doing a job, pk, spar, basing and event can hear the sound while to play Graal Era. So, If the most players are boring for with regular music or sound to around the era? You need to play music or sound with another devices for less boring and excitement. Well, it's okay nevermind that if don't understand what I saying. and okay right here that's I like my 2 soundtrack to able concentration.

1st Soundtrack: https://m.youtube.com/watch?v=f00W3U6mb_M
