So Rock Band 4 is out tomorrow right? Are you happy with the soundtrack?

I am especially looking forward to:
Mark Ronson ft. Bruno Mars - Uptown Funk (regular soundtrack)
Duran Duran - The Reflex (for PlayStation Network Plus members who pre-order via the PlayStation Store)
"Weird Al" Yankovic - My Own Eyes (for people preordering a digital copy on Xbox One via Xbox Live)

Any idea when I should expect them leaking?
