Apple One membership is a gem in the subscriptions world:
Starting with Apple One, I think is more convenient to pay one subscription for a lot of services rather than paying only Spotify for one service. With the Apple One Family plan, I have 200GB of iCloud storage, Apple TV+, Apple Arcade, and Apple Music, and I can share all of these services with my family. For $19.95 a month, I have way more benefits instead of paying $9.99 per month for Spotify individual plan or $16.99 for a family subscription that only includes the music service.
Also, from what I’ve noticed, the music quality is significantly better in Apple Music.
