I just discovered that there are 14 new BGMs added on last week’s patch. I am not sure if these soundtracks are for the new maps coming along with Rank 8, or for the extant instanced dungeons (the Weekly Q&A mentioned that all dungeons’ musics will be changed).
Here’s the list of all new 14 BGMs:
SoundTeMP - Exotica
SFA - La Valle della Morte (this one has 13:49 duration, epic!)
SFA - Hunter Green
Kevin - Victor Quest
Kevin - Stance on a While
Kevin - Run Run Run
Kevin - Red Warrior
Kevin - Peripeteia
Kevin - Defiance
Kevin - Crush or Nothing
Kevin - Cordis
Kevin - Black Flag
Gaudium - Undercover
Gaudium - Tekknobonk
Edit: For those who love this game’s music as I do, you can listen to all these new soundtracks here.
