 Do note: This removes all songs from the playlist and readds them in a shuffled order... Do not stop the application before it finishes or songs will go missing. It will also reset the "Added On" date for the songs. Also, Spotify apparently has to redownload the songs for offline play, even though they were only removed for a couple seconds (However, this may only check the file system and skip over the songs that are already downloaded as it seems to download 500+ songs very quickly). Use at your own risk, I just wrote this to shuffle my playlists up and thought I might aswell release it.
