Since the launch of the Nintendo Music app in October of last year, Nintendo has consistently been expanding the service (free for Nintendo Switch Online members) with more soundtracks from their extensive library of games.
Today’s update includes over two hours of music from New Super Mario Bros. U Deluxe, with 90 total tracks added. A selection of curated playlists are also available to help keep the sizeable variety of songs and genres organized, including Worlds, Courses, Battles, and an Extended-Playback Collection.
Nintendo Music is available now for iOS and Android devices from their respective app stores.

I forgot about this useless app. I wish they would get Pokémon Colosseum music on there or make the app have access to Android Auto and Apple CarPlay. but they wont listen that’s why i forgot about the app.
Please give us Mario kart world soon as possible, at least lets us buy it as a CD cause I would love to hear every single song without the loud background noise.
They will never let you buy things. Just keep paying.
The fact they didn’t add this app to the Switch 2 to be able to listen to while playing anything is stupid as hell on their part
With it being modeled after the Spotify app, it’s definitely a shame they didn’t copy that feature for Nintendo Music, too.
I hope they gave us Mario Kart Double Dash or World next.
Bop, bop bop.
