apple music subscription

Apple Music is not included with the Apple TV+ subscriptions. They are separate and independent subscriptions.

Any active subscriptions to Apple services would appear on your Apple ID when following the steps below:

1. On your PC, open iTunes.
2. From the menu bar at the top of the iTunes window, choose Account, then choose View My Account.
3. Scroll to the Settings section. Next to Subscriptions, click Manage.

No, as I said, Apple TV and Apple Music are separate subscriptions. One would not refer to another for any reason.

If its saying you are already subscribed to Apple Music, then you are subscribed to Apple Music.

Does the subscription not appear when you follow the steps above?
