SpotiSqz connects you to Spotify and lets you see the state of your Spotify playlists and tracks at a glance. You can see how many playlists you have and what their relative sizes are. You can also view the state of another users playlists (provided they are public). You can email yourself a list of all your playlists and tracks.
Tap a playlist square to see all its tracks at once. You can see which tracks are in multiple playlists, and list and visit those playlists. You can easily move tracks around within a playlist, or copy or move them to other playlists. You can bulk copy the contents of another users playlists to one of your playlists.
If you can play music using SpotiSqz (requires Spotify premium) then SpotiSqz makes it easy to locate the tracks you want to play because you can see all your playlists at once, and all tracks at once for a playlist.
There is also a search option which lets you search all your playlists, or scroll through your recently played tracks. SpotiSqz also shows which tracks you have already played (and can filter on this), making it easy to ensure that you have listened to everything when you are exploring a new playlist.
Repeat option lets you repeat a selected amount of times. Repeat also has the option to repeat a group of tracks.
