MOON was released after the scandal, so the reason why it may not sound like too "elementary" might be that she was depressed at the time. I think she didn't have that passion that she usually does when that single was recorded. Personally I still love it a lot, only reason why this single is my least favorite is That Ain't Cool. I can't stand that song because Fergie sings in it. Other songs are great, especially Moon Crying and Lady Go!.
Oh, and I want to listen to GTTT already! I wanna hear darling in full. ;_;
