What mods do you enjoy using that adds to the fallout 3 wasteland experience?

I am looking for a mod that adds to the selection of background music (not radio station mods) while I am exploring or in battle. I use FWE as my overhaul mod if that helps. So immersion music would highly be welcomed and prefered!

Thank you

http://www.fallout3nexus.com/downloads/file.php?id=7274 is some of the best atmospheric modded music I've heard for a game. I don't use the battle music from it, but the public tracks et al are astounding.

gyshall, thank you so very much for making this suggestion I grabbed the file and from reading the description, I am excited to test it out Since you don't use the battle music, do you have a suggested mod that I can grab the battle music from?
