Background

On Spotify, users can create and manage playlists. On the Spotify app or website, users can navigate to the "Your Library" section and click on the "+" sign to create a playlist. When creating a playlist, users can add music tracks to the playlist.

After a playlist is created, users can add new tracks to this playlist, or remove tracks from this playlist. Users can also move tracks to new positions within a playlist. The following two images show the moving process:

At first, track 1 is "Perfect Duet", track 2 is "Always Remember Us This Way", track 3 is "Million Reasons", and track 4 is "I'll Never Love Again".

Next, we drag track 4 up to right above track 2.

After this dragging action, now, track 1 is still "Perfect Duet", track 2 is "I'll Never Love Again", track 3 is "Always Remember Us This Way", and track 4 is "Million Reasons".

Next and Previous Button

When using Spotify, if users press the "Next" button, Spotify will skip the currentlyplaying song and starts playing the song that is listed directly after it; if users pressthe "Previous" button, Spotify will go to the song listed directly before the currentlyplaying song.

The following images show the behavior. of pressing "Next".

Before pressing "Next", the currently playing song is "Always Remember Us This Way":

After pressing "Next", the currently playing song is now "Million Reasons":
