Music from the Wrath of the Lich King login screen

Allegedly, this is the music that you'll hear at the Wrath of the Lich King log-in screen. I love it! It achieves just the right blend between savage and graceful, haunting and heroic, and of course it contains the main WoW motif that we all have come to know and hum at inappropriate times (or is that just me?). I've seen this file in a couple places now, and if it is fake, it's extremely well-done. Kudos to Blizzard, assuming it's not fake; this is another piece in a long line of great atmospheric music.
