Colony - In Flames.
It's been ages since I last heard this song. It's great, though; every time I listen to it, I always get motivated. This has gotta be the best song of In Flames, in my opinion. (: They have other great songs, but nothing compares to this. If you're a fan of metal music, then you should definitely give it a listen. If you have already, then listen to it once more! Haha.
