Well, after having listened to the full album, I can safely say that I'm gonna be skipping The Inferno on subsequent plays and replacing StU with the single version. Other than that, the album is pretty damn groovin'. I don't quite understand all the hate for Phenomenon either. I expected it to be COMPLETELY different based on the preview (it was my favorite out of all of them), but in the end I'm still happy with the full song just because it sounds so unlike the 'usual' Dir en grey.
Getting some major old school vibes from some of the guitar parts in Cause of Fickleness too, good.
