I wanted to be able to randomize my playlist order in a more permanent way. I know there is a shuffle option but when I shuffle and continue playing on my phone, it re-shuffle's the playlist so I'll sometimes keep hearing the same songs over and over.
Once you authenticate with Spotify, your playlists will appear below. Select a playlist to change the order of songs and wait for a message. Easy peasy. Once it completes though, it can't be reversed by this tool. So make sure the list you want to change the order of is the correct one.
