Pandora's great at finding new music, and Spotify's great at managing your music collection. Wouldn't it be great if you could use them together? Pandify can help.
Pandify can scan all the tracks on Pandora you've given a thumbs-up to and creates a playlist. You can filter the list by genre to remove anything that doesn't fit the kind of playlist you want. You can also download a text file with the track listing if you want to try to import it to another service, though only Spotify is explicitly supported.
