Did a quick Google search and found a Yahoo Answers post for it via [link]. The last suggestion has a link to an MP3 sharing site that had several hits showing for "The Walking Dead". Only issue is that since there is also a show with it's own soundtrack these MP3s may be those or directly from the game.
Also, the last song (haven't started playing my copy from Steam's last sale so I have no clue what they are talking about) is listed as "Take us Back" by Alela Diane and can be purchased from iTunes.
