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 an hour and a half of music from Clubhouse Games: 51 Worldwide Classics, with 115 total tracks added. A selection of curated playlists are also available to help keep the sizeable variety of songs and genres organized, including Top Tracks, Card Games, Board Games, Sports Games, Variety and an Extended-Playback Collection.
Nintendo Music is available now for iOS and Android devices from their respective app stores.

What an odd upload decision- I’m not sure many people paid attention to the soundtrack for that game.
Though there is one piece I remember distinctly. I think it’s the Connect 4 game that has a music track that sounds like it was ripped straight out of Spongebob.

Dude, what is this? I can’t imagine going “Oh! I can’t wait to hear my favorite club house 51 games soundtrack again :B”
