I’m actually surprised the record labels are allowing Apple Music to be part of any bundle. It‘s obviously going to be propping up all the other services.Imagine that, a bundle option right before those one year free subs for Apple TV+ are set to expire.
Standard damage control. When services are not treading water, bundle them with ones that are surviving on their own. No one wants Apple News or Apple Arcade, the numbers show that. And, Apple is afraid that when those free Apple TV+ subscriptions lapse their retention rate is going to be abysmal. So, bundle them all with Apple Music since that service and the App Store are generating the lion's share of the services revenue.
Always be wary when a company doesn't release what their subscriber numbers are. They are hiding something.
