While all of Spotify’s 3 million paying subscribers have access to the company’s mobile app, iPhone users get the added bonus of streaming at the near CD-quality rate of 320kbps. For the sake of their data plans, Spotify Premium members can also listen to their playlists offline, plus they have access to all of the site’s great social features like the ability to share playlists and post what they’re listening to on Facebook.
