Greetings l16n,
You are able to hide music from your followers using these steps:
"Hide music from your followers
- Tap Listen Now, then tap
or your profile picture. - Tap View Profile.
- Touch and hold the playlist or album (below Listening To).
- Tap Hide from Profile.
The listening history for this item won’t appear in your profile or be visible to the people who follow you. If you don’t want your followers to see any of the music you listen to, tap Edit on the profile screen, then turn off Listening To at the bottom of the screen.
Note: It may take up to 10 minutes before music you hide is no longer visible to your followers." See what your friends are listening to
However, if someone saved those songs or added them to another playlist, they would still have access. When you hide your playlist, future edits would not be visible.
We hope this helps!
Sincerely.
