I have an idea for a mod for FO3, but not to sure how to make it, or if it can be done. Basically I want the soundtrack to stop playing, so theres nothing, just the sounds. I.E. if im exploring the waste's i want no music, but only to played once every hour or so. Kinda like Minecraft on PC. But I always want music when im in Megaton and Rivet City. Is there a way of doing this? Sorry if i havant explained this well. Its just an idea for immersion, to get that lonelyness feel of the apocalypse.

You could replace all worldspace, dungeon, and battle music with blank .mp3s, though I don't know if any of them would be shared with "settlement" music.
