Audience Part 2: Music thoughts

I want my video game to provide a chance to escape for my audience and so I am also looking at importing engaging, mystical and almost fictional music and sounds into the game in order to contribute towards this purpose and to help the player forget where they are. I am not sure if I will be able to add music that contributes to the sin of the level but I will look into it after, as the music would also help to incorporate the type of genre I want to be felt in each level. Dark, slow and eerie for horror, fast paced, jumpy and alive for action/adventure, soft, flexible and hopeful for fantasy and so forth.
