I agree that that track is amazing. I spent a while searching for the songs in the pre-show last year and found a list on Amazon.com pointing to the songs (and CDs containing the songs) in both the '99-'04 preshow and the '04 to present preshow.

However, it is missing one song ("Red Skies") from the current preshow, according to the lists at
http://pages.prodigy.net/stevesoares/il ... reshow.htm and at the aforementioned Disney Music Loops site. It also does not include "Appalachian Morning" by John Williams, which plays at the end of the '99-'04 preshow and is of such a different character to the rest of the preshow music that it almost feels like part of the show.
The track on Subsonic is the '99-'04 version and contains all ten preshow songs of that era, including the aforementioned "Appalachian Morning." All of the preshow songs are prepublished. Once the show starts, the rest of the track is presumably original music, written for Illuminations: Reflections of Earth or for the Millenium Celebration (namely Don Dorsey's song "Promise," played immediately following the show, and the score for the Tapestry of Nations parade).
I'm not that familiar with Tapestry of Nations / Tapestry of Dreams, but I will say that the cue following "Promise" in the Evening at Epcot track matches the music about 5 or 5 1/2 minutes into the Subsonic track "tapestry of nations (with exit music)," and I believe they match all the way up until the latter track ends, which leads me to wonder whether that track from Tapestry of Nations isn't incomplete.
Just before the end of An Evening at Epcot, there's a clock ticking that's reminiscent of the opening of the Tapestry of Nations track. That, coupled with the fact that the Tapestry of Nations music offered by Disney on CD is closer to 25 minutes long (versus 14 on Subsonic Radio), suggests to me that the remaining 10 minutes in the Evening at Epcot track might be from the last ten minutes of Tapestry of Nations on the CD, which are in turn cut off of "tapestry of nations (with exit music)" on Subsonic Radio. I haven't heard the CD, though; does anyone have a Millenium Celebration CD to do the comparison?
Interestingly, the end of An Evening at Epcot is also similar to the end of the "tapestry of nations" (not with exit music) track on Subsonic.
As to who put together the track, I couldn't say, although I always thought it was a master as opposed to a fan recreation. It sure sounds professional; whoever made it did a great job. I've seen a version of it that claimed to be encoded by sds910, who apparently also contributed the tracklist to for the preshow to the Prodigy website above.
As an aside, I liked the Väsen song (heard during the 5 minute announcement) so much that I bought their CD from Amazon -- not the Northside Sampler mentioned in Tropi's list, but the band's CD "Whirled." All of the songs on it are quite good! They also used to have 3 free song downloads on Amazon, but I can't seem to find them any more.
