I can't find it online anywhere, but my favorite song in the entire game in the one that I heard for the first time in Eregion. It has a very "ancient, lost empire" sort of feel to it.Starts really soft and pleasant, then takes off and get louder and louder with more drums and power.

There's a version that's much to short and over-edited that I've heard before in housing music. I love that song. And like I said, I've never found it online outside of the game. It also doesn't exist on any of the official music options over the years.

Sorry for the terrible explanation, but it's hard to describe a song without lyrics. I'm assuming a lot of people will know what I'm talking about though. The song is epic.
