This game had a great and touching soundtrack. I'll list all the songs used in the thread for reference.
Main Theme - Plays when we are introduced to Lee.
Alive Inside - Plays when Lee and Clementine look over what his parents left behind, and many other moments with Clementine
One Choice - Plays when you must decide who to feed in Starved for Help
It's Over - Plays when you leave/kill Andy and if Ben is dropped.
Message - This plays when Diana's message is heard at the house.
Safe - This is a puzzling one. This might play when walking around the St. John's, and when Lee is burying Fivel.
Tension - I have no idea when this plays. I can tell you one thing though. It probably is in a tense scene.
Honest - This plays when the boat is found.
Spirit Healing - Played by Chuck on his guitar
The Best for You - This plays when the group decides what to do after Clementine is kidnapped.
Decision - I dunno.
Falling - Meet Fivel. Looks like Duck don't he?
Outcome - Kenny and Ben's final stand.
Armed With Death - No explanation needed.
Saved - I don't know.
Goodbye - Keep that hair short.
Take Us Back - The reason we all burst out crying even after it finished.
400 Days - The song that made watching the DLC trailer all the better.
Baltic Sea - The song playing in 400 Days' introduction.
Walk Among the Cobras - What would you rate this song? Strong six?
400 Days Credits
Truth Witnesser - Meet the parents.
