Music and sounds

[Kiwi2703]

Hello there
I'd like to ask you a general question about using music and sounds in custom stories, because this is the only area of interest left that I am not really sure of.
What's the best way to create (put in the story): 1) general music, 2) sectional music, 3) occasional sound effects?
I mean - should I place the fancy speaker icon in level editor with some music in it above the area to create general music for the area? Or should I script it directly into the player's ears?
Because music is half of the atmosphere of the game, I would really like to know the best way of placing and using it in my custom stories.
Thanks for any responses and solutions!
