The reason Obsidian won't include custom tracks is TSL game is going for a cinematic experience where the music and story work together to create the best possible level of immersion for the player. They want the player to have an emtional investment in the characters, the story, and most of all they want the player to forget their playing a game all together. This can only be accomplished with deep characters, story, and a score that sets the mood for what is transpiring on screen.
Cheers!
