It's really amazing how songs can sound differently even though they basically are the same. This really isn't that much different from 2.6. It still has the same catchy melody and same song progression, but it still sounds like a completly new song due to the use of different instruments and different mixing.
I like the outro a lot better here, though. I think the "slowing down" is very well done, and I've always liked it when the final notes ring out. :D
