I decided I wanted to do an extended remix of "symmetry", but when it was done I realized that the new version didn't fit the title. You see, in the original version, the song structure is actually symmetrical. It starts with one layer, and new layers get added one by one, and after the peak the layers get taken away in reverse order. The new mix didn't have any symmetry at all, but I couldn't very well change the name since it was simply a remix and not an entirely new song.
