Today Apple announced a new cheaper subscription for Apple Music called the Voice Plan which is $4.99 a month.
The Voice Plan uses Siri to play music from Apple Music on your iPhone, HomePod mini, Apple Watch, and etc. This plan doesn’t give you access to the Apple Music app with a catalog of songs and artists you can listen to but uses Siri instead to play music based on what you’ve listened to before.
Apple will offer this plan alongside the Individual plan for $9.99 and the Family plan for $14.99.
