Personally, I was more suprised by the wii sports music and all the pink.

AFAIK, that is music made by Marcan (Lina) him/her self. Amongst other talents, Marcan also appears to be musician. There are a few interviews with Marcan where you can see pianos in the background, for example here: https://youtu.be/dF2YQ92WKpM?t=989

He/she is quite the creative person I must say.
