Apple Music contains a vast quantity of Spatial Audio tracks, but it isn't easy to find them. That's why I built The Spatial Audio Database, the only website that lists every Spatial Audio track.
Previously, I posted upgraded tracks and albums to the @NewSpatialAudio Twitter Account but unfortunately the recent takeover by Elon Musk has resulted in my API access being revoked. This site is still a work in progress, but for now you can view all tracks that have been upgraded recently as well as being able to download daily data exports.
In future you'll be able to search the entire Spatial Audio database by artist, album, or track; in the mean time, I'd encourage you to use my Spatial Audio Finder website if you're interested in seeing what music has been upgraded for a specific artist. You may also be interested in my Music Library Tracker app for iOS which can tell you which tracks in your library have been upgraded.
You can subscribe to my free newsletter if you want to know when new features are added. If you have any queries or run into any problems, please get in touch.
