I was going through the music files for Oblivion, located in the Data folder, and I noticed that the "atmosphere_5.mp3" file seems to be missing. Was this intentional? Or am I literally missing the file?

Also noticed "atmosphere_2.mp3" is missing as well. (I probably should have noticed this one before the other one, but meh, wasn't looking for it back then.)

Seems normal, if my setup's anything to go by. :shrug

edit: And if you're ever suspicious (or sure) that you're missing any of the official music, you can get it back http://tesnexus.com/downloads/file.php?id=20251 anyway.

Isn't the music contained in a .bsa archive in any event?

That's normal. Don't worry, you have all the Explore music if you're missing 5 and 2.

@HeyYou. The music was provided loose, it was never packed in an archive.

Ah alright, thanks for clearing all of that up. I became really curious when I noticed this, as I wondered what the "missing" songs must have sounded like, and wondered what made them cut them out, assuming they did. Anyways, thanks again.
