Labels are useful for organising your library. You can add as many Labels as you like, and every Song can have as many Labels attached as you need.
To update the Labels attached to a Song, you can open the Song from the home screen and scroll down to the Labels box.
This displays a list of the Labels you have created. Tap a Label to toggle it on or off for the current Song.
You can also use the “Create Label” button to create a new Label here.
You can view, create, update, and delete all your Labels in the app settings.
