Over 400 music tracks

This is a picture someone took during the 50 facts vide0.



I think there might be an even 500 after all the music is unlocked though since that bar want way up in the video.

That's a lot! Compare it to most other Wii U games, and there's like 5 times the amount of songs. I guess the soundtracks you get from Club Nintendo for owning both versions probably won't include all of the songs though. :/
