Oh. Also, does anyone know what song is played for the end credits?

This was your first mistake :P

I don't bother showing my close friends my music cause they just won't listen to anything with female vocals regardless. At least it seems that way.

It's mentioned elsewhere in the thread (I think I did....) but anyway, it's George Gershwin's Rhapsody in Blue.

Which leads me, sort of offtopic, to this piano+tap version that amuses me:

Hiromi Uehara - Rhapsody In Blue with Kazunori Kumagai's tap dance

I wish she would record a studio version of it.

Re: Sweet Spot, one of the best things about SR is when she can’t really pull off something convincingly, but then she strains herself to the limit trying so it kinda works anyway. It’s like hardcore fakeness or something. This has always been present, but with MM/SS it kind of went with the ’rock’ thing. But then she does it with Nu-er stuff like Sweet Spot or Ryuukou or Roudousha, and the effect is quite neat.
