This is a composition that was included with the AoW demo, but for some reason it wasn't included in the main game. It is very nice, and contains some themes used in some of the other songs and some new ones.

You can either place it into Age of Wonders\Songs and add it into the in game playlist or you can install a mod file plugin for Winamp and add the file, the rest of the Age of Wonders music and anything else you might fancy and run it in the background.
Age of Wonders is very Alt-Tab friendly.

It's a pity the song wasn't used in the final game. Besides "In the Company of Elves", the demo also had different versions of "Victory Sunset", "Carved in Stone", and "Love and Death" (one of my favorites). Its version of "Defenders" is normal.

Here's the lot of them if you don't want to install the demo.

Just download, name them as you please and drop them in the correct folder (Songs). Then tweak your playlist in-game.

Yeah, demo version of Love and Death is really great.

I didn't know that. Thank you! I love "love and death" so this will be really interesting.

Interesting, thanks for sharing!

Does anybody have these extra songs already converted to mp3? If they are handy for dl'ing, it would save me from converting them myself. Thanks.

Thanks will definitely check those out
