Just got my order from Club Nintendo yesterday, and I was as happy as a kid in some kind of store.
After listening to it carefully twice, I can conclude that this is the best Mario music I have EVER heard, as well as being the best soundtrack of 2007, I love it to DEATH. And beyond.
Also, since this is a Club Nintendo only dealy, and I hate seeing lots of people trying to earn money over it when Nintendo is too arsed to just sell it, I have ripped it and put it up at sendspace for your aural pleasure:
It has every track that has live instruments in it, not just the actual orchestral ones, PLUS it gives you the new synth arrangements of Athletic from SMB3 and the original Mario theme, meaning that this CD actually has ALL the themes I needed.
