The Grooveshark music streaming service has been shut down without previous notification. I had many playlists that I would like to recover (playlists I made over several years).
Is there any way I could recover them? A script or something automated would be awesome.
You can access some information left in your browser by checking the localStorage variable.

Go to grooveshark.com
Open dev tools (Right click -> Inspect Element)
Go to Resources -> LocalStorage -> grooveshark.com
Look for library variables: recentListens, library and storedQueue
Parse those variables to extract your songs

Might not give your playlists, but can help retrieving some of your collection.
How can I make a script to recover my Grooveshark playlists now that the service has been shut down?
