Nintendo has thankfully seen fit to add additional Free Roam tracks to Mario Kart World on the excellent Nintendo Music application on iOS and Android. The tracks from Super Mario 3D Land, Super Mario 3D World, and Super Mario 3D World + Bowser’s Fury from the Free Roam mode on Mario Kart World are now available to listen to. Nintendo Music is a free app but an active Nintendo Switch Online membership is needed to listen to it.
Thanks to Jason F for sending in the news tip!
