Organize your Spotify playlists on your android device
It is currently not possible to manually reorder playlist songs on the android Spotify app. (See here.) This app allows a user to log into their Spotify account and edit their playlists. It was built using the Ionic v1 framework.
Source code for the app is located in the src folder. I used babel to transpile that ES6 Javascript to ES5. The ES5 code is located in www/js.
