Earlier this year, it was revealed that  Apple is working on new Music, Podcasts, and Books app for macOS. The Music app to be included in the next major version of macOS, 10.15 was to be made using Marzipan, that lets iOS apps run on the Mac. Sources close to the developers reached out to 9to5mac and provided some interesting tidbit of information.

The new standalone Music app on macOS will be an AppKit application, based off of iTunes. As a result, it will come with a plethora of features that come with iTunes applications. Some of the features will include things such as smart playlists, advanced library management, syncing with iPods and iOS devices, and even disc reading and burning.
