How can i access mod's files?

[radiant vortex]

I only want music, is it possible to extract it from mod's files?

C:\Program Files (x86)\Steam\steamapps\workshop\content\312520 is where workshop mods files are stored

they'll be in folders with the mod's workshop ID, which is at the end of the steam url

then you'll want to look in music/songs
