Here another way to rescue your many lovingly curated GrooveShark playlists. It a new music service dat imports your playlists and finds YouTube equivalents. Don't forget to follow da boi!
Note AudioSplitter only import 10 playlists at a time. Plus dey a several-hour waiting list and long playlists have to be imported several times to get the whole list. Sometimes da YouTube video isn't quite the same. Maybe a different artist or a song wif a similar name so be sure to proofread.
But still. Better dan losing all dat music.
