Thingify is a Spotify add-on for Android. It allows you to manage your Spotify playlists from everywhere even your lock screen. This app will connect to the public Spotify API and download your playlist information. You select some of your playlists in the app which you want to manage. You can only select playlists that you own. When you start playing a song in your Spotify app Thingify will send a new notification. This notification displays all previously selected playlists with their associated image from Spotify and whether the currently played song is already on it or not. You can add or remove the song with a simple press on the specific playlist icon. Thingify also works offline and will update your playlist as soon as your device reconnects with the internet.
