Can I Listen to Spots on My iPod?
For you? Sure!
SpotDJ has a (currently experimental) feature that lets you take spots to go. Simply click the small iPod button near the top of the SpotDJ window. It looks like this:

Now you’re in iPod mode. You’ll see a drop down menu with a list of your current iTunes playlists. Pick the playlist you’d like to add spots to and then click Create Spotted Playlist. SpotDJ will create a new playlist with spots based on the original. Your original playlist will be left untouched.

Now, just sync your iPod to download the new playlist and you’re ready to take your spots on the go!
