iTunes continues to work on older versions of macOS and Apple has so far left the Windows version functional and intact. While iTunes may be dead in the newest versions of macOS, it still lives on elsewhere. The iTunes Music Store also lives on inside the Music app, giving you the option to purchase your music instead of subscribing to a streaming service. While Apple Music is a subscription service that costs $10 a month much like Spotify, the Music app on iOS doesn't require a subscription and now performs the duties that iTunes had before it, including syncing. Accordingly, your iTunes library as you knew it, with all your purchased music, should be available inside the Music app, which you can find with a quick Spotlight Search if you hit Command + Space Bar and then type in ' Music.' With the demise of iTunes, the Music app has inherited some of the older apps features.
