Ipod Shuffle and Spotify Premium

[andyla]

Spotify help says that Ipod Shuffle should be able to sync with spotify:   "Spotify supports streaming and offline syncing to iPod touch versions with iOS 5 or later. You can sync only your local files to the following models: All iPod classic, nano shuffle, except the very early Firewire versions. You will need to install Spotify on your computer to sync music to your iPod. You can download the desktop app from www.Spotify.com.",   but I can't see how to sync downloaded files with an ipod shuffle. Can anyone help?
