Yes, "Letters From the Sky" by Civil Twilight has been used in a lot of places, but man. Listen to those lyrics... You can't tell me that's not The Hunger Games. It's a great soundtrack--but it would've been better with Letters, just my opinion.
Any song you wish had been included?
Hope you enjoy,
P.S. LOVED the movie!!! So good I've already seen it twice...and am planning to go a third time :D
