I know ToS music is not for everyone, but for me, it has some of the best soundtrack in the ocean of MMORPG out in the market.
Some other notable MMORPG that I have played in the past with outstanding music are Maplestory and Final Fantasy 14: A Realm Reborn. They are different genre of music but still, Tree of Savior’s choice of music is really unique in it’s own rights. Who would have thought electronic/dubstep/trance-like music would work in an MMORPG?
Here goes the only two I can think of right now:
Dungeon BGM: https://www.youtube.com/watch?v=tUKfStEXf7Y (Emiya theme from Fate/Stay night anime)
Boss BGM: https://www.youtube.com/watch?v=FlnoM89dmsw (Vergil battle theme music)
