There are currently 3 known PARALLEL ROTATION folders: IIDXRED, HAPPY SKY, and DistorteD. In each one, there are 3 pre-existing songs, and then a new semi-derived OMES.
Here's the DistorteD OMES: A 嘆きの樹 remix/sequel called G59.http://www.youtube.com/watch?v=pS0GA0uN3R0&fmt=18
I'm expecting GOLD, DJ TROOPERS, and EMPRESS folders for PARALLEL ROTATION #02, and ALL STYLE or something for PARALLEL ROTATION #03, filled with past ES's and OMES's, with an OMOMES to top it off. In short, a perfect ES system for this 10th anniversary mix.
(God, I sound like an infomercial)
