You can probably recover your playlist. (Instructions for Chrome)

On the computer you used grooveshark on: visit the website, open developer tools, open "resources tab", click on local storage->grooveshark.com. Now find the key called 'libraryXXXXXX' where the X's are numbers. Right-click it, "edit value" and copy/paste that data here: https://json-csv.com.

I just made an account on this site so I could tell you this, but you just saved the last four years of my music collection. I can't tell you how incredibly thankful I am right now.

Late, but if your library gets truncated because it is huge like mine, you can instead get it by opening the console and typing JSON.stringify(localStorage); while on grooveshark.com
