Ok, here's my soundtrack for TGS.
It works better if you remember to layer, for instance, a low volume thunder track with a music track when the characters are in the Thunderwater inn.
The thunder volume can (and should) be turned up when they are closing in on one of the stones.
One effect of using this soundtrack was that, after hours of listening to it, the players were really getting weary of the constant thunder and rain
- a good spot to advance the party tension meter
