Apple pushes its Music subscription service heavily, to the extent of killing off iTunes in macOS with the release of macOS 10.15 Catalina in 2019, and replacing it with several apps, including one simply called Music.
But if you subscribe to Apple Music, you might find you can’t purchase music, only listen to it. Apple has retained the name iTunes just for purchases, as in the iTunes Store, and disables showing results from it by default when an Apple Music subscription is active. (I checked among my family after we subscribed to the new Apple One bundle, and none of us had iTunes Store active any more.)
