About
There are some neat little tricks you can use to maximize the potential of the new feature. For example, if you know the names of the artists or songs you want to listen to, you can enter them directly into the provided search box. If you haven't saved a track, you can click the + sign by the left of the playlist and choose the save button. The code will automatically save the track for you and then the photo-sharing app will display the link in the corner of the screen.
