What are your thoughts on the MKWorld OST so far? (+Fanmade Leitmotif for NS2 Rainbow Road)

If there's one thing I'm excited about with MKWorld, it's the new soundtrack!

So I want to know, what are your thoughts on the MKWorld OST so far?

+I'm no musician, but here's a little 'Leitmotif' I came up with that I wish was a part of the currently unrevealed NS2 Rainbow Road theme. (It's a homage to the main melody of Wii Rainbow Road!)
