Had to join just to say: Sorry haters, this sounds pretty legit.
To the people complaining about the track length, it's slowed down 16x. I can't be arsed to crunch that into percentages, but 16x stretch makes the same 36 minute song that is on soundcloud.
If you download paulstretch (http://hypermammut.sourceforge.net/paulstretch/), download u smile (http://www.mediafire.com/?nnymymazten), and put one into the other and slow down by 16x, it's nigh-on identical to the soundcloud one, at least at the beginning. I don't have the programs or the know-how to run any kind of difference filter on the two things but they sound close enough.
Also a friend found this (http://www.youtube.com/watch?v=Qica4VQZHnA&feature=player_embedded#).... not sure how much can be accounted to loss in quality during the process but it's close enough to convince me.
