Just got back from watching this film...and I noticed a couple pieces of music toward the middle and end of the movie that I recognized from another film.
SLIGHT SPOILERS: When Neeson's character flashes back to the time he was a boy, the same piece from the film Ink is used. I looked at a tracklisting for The Grey and didn't notice this song on there, so if you watch The Grey, hear this music and like it, then check this track out:
Ink - The City Surf (Soundtrack) - YouTube
The part you hear in The Grey starts around the 47 second mark.
