You can see in the credits that most musics were made by Alexander Monakhov aka Massage/DJ Mohax, and some by Alexander Machugov aka Manwe and The SandS. I saw on this forum years ago that the first have some personal problems that prevent him from making new ones, which is unfortunate because there are a few musics from original totem tribe that didn't get a remix, especially the one on islands where you fight skeletons.
You can listen to all the musics by going in your game folder in Totem Tribe 2-game data-sound-music and Totem Tribe 2-game-data-sound_opt, I recommend listening to some music at twice speed (without higher pitch, you can do that using vlc and clicking on "faster" playback speed twice), mainly "path to the stars" which sounds incredibly better, same for the music you hear in the opposition hideout. Enjoy it while it last, because if you are like me, you will listen to them over and over until you no longer enjoy them.
