However, according to developer Steve Troughton-Smith, he claims that there is a good chance that with the next macOS update, which should be announced at WWDC 2019, Apple could finally be breaking up iTunes into smaller and more manageable apps that will vary depending on what you need them for.
According to Troughton-Smith, “I am now fairly confident based on evidence I don’t wish to make public at this point that Apple is planning new (likely UIKit) Music, Podcasts, perhaps even Books, apps for macOS, to join the new TV app. I expect the four to be the next wave of Marzipan apps. Grain of salt, etc.”
Apple might have actually hinted at this last month when they launched their new Apple TV+ service and where they revealed that a new TV app would be launching for Mac. Previously we would have imagined that Apple would have just stuffed the TV app into iTunes, but the separation hints that maybe the break up of iTunes could finally be happening. However, until it does, take it with a grain of salt for now.
