Does anyone know the name to this song??

Question

if you have seen the movie "the departed" it is the song that they play throughout most of the movie. It has an irish feel to it.

Answer 1

Checkout the soundtrack here at Amazon. You can sample the songs and find the one you are looking for:

You can also checkout the score to the movie. Which is much more likely to be what you are looking for, but these don't have audio samples.
