How to see how long you listened to an artist on apple music
Answer : Apple Music users can access their data, via the "Replay" feature, in a few ways. To simply access the playlist of your 100 most played songs, go to the"Listen Now" tab in the Apple Music app and scroll to the bottom of the page. Once there, you'll see your Replay for 2020 and every year you've had Apple Music.
Hope this helps you!
