There are 14 different Spellcraft tracks now. Some feature a made up celtic like language,but as far as I know it is not real.
The tracks are:
Descent into chaos (theme music)
Court of the fey queen (forest)
Halls of the underking (Underworld)
Krakens reach (Ocean)
Shimmer reef (Ocean)
The floating isles (Air)
Temple of the snake god (Jungle)
The spawning pools (Dream spore)
Rise of the mages (Air).
all is lost (if you loose a game)
