This is one of my favorite songs from The Killers. I enjoy their music quite a bit but this song probably along with Shadowplay are my favorites from them.
Maybe it's because I don't hear it as often as some of their other stuff but I love the rhythm and the lyrics and everything. I can slip this song in between a couple of other, harder songs like stuff from say Rage Against the Machine and it will fit in nicely. This song has helped me in outdoor runs and at the end of interval runs. It's funny how you can remember certain parts of certain runs because you listened to a particular song and can conjure up the memories.
Anyway, here's the video for For Reasons Unknown:
