If you want to delete any song from the user created playlist, then you will need to follow the steps below:
- First you will navigate to the library and head to playlists
- Select the playlist you will need to edit
- There are three dots on the top right hand corner that you will tap
- Then tap edit option
- Afterwards, tap red circle that is next to the song that you want to delete and then tap delete
If you swipe left to any individual song that is in your playlist, it will not remove it from playlist and only removes from library.
