re/spin imports your playlists from Last.fm and Spotify to Rdio with just a few clicks. If you’re on Last.fm, either enter your Last.fm username or playlist URL to select and transfer your mixes over to Rdio. Spotify account holders will need to batch select tracks in Spotify, copy (ctrl+c or cmd+c), and paste the links into the re/spin text box to import. re/spin can help you organize your plethora of playlists to one central location on your favorite music source, Rdio.
