If you use both Pandora and Spotify, listen up. The Next Web recently highlighted an extension for Google Chrome called "Pandora to Spotify Playlist Converter."
Basically, the free add-on takes the music you've liked on Pandora "and turns them into playlists on Spotify," writes The Next Web. "I can't even begin to tell you how cool this is."
It sounds like a great tool to bookmark songs and artists discovered on Pandora for on-demand listening later.
