I do. I noticed the removal a little while ago and was just curious about what happened, so I mentioned it in this thread.
Can you describe what the difference between the two soundtracks is?
The size difference (81,6MB - 52,4MB), same musics (except that there's no Maybe
in fallout_soundtrack_2), and a slight difference in duration (some tracks have 3 seconds more).
If you really like Fallout OST, you can download for free (legally) the remastered soundtrack here (by Mark Morgan): http://auralnetwork.com/releases
