* New: Friendlier login for first-time users.

OK, now they need to update the Android version to have support for saving offline tracks on the external sd card.
Will this app support the original iPad after iOS 6 rolls around?
I’m not sure at this point – I would hope they would continue to support it!
The most wanted feature FOR YEARS by users with iPhones and Spotify is to be able to sort playlists by artist etc. Spotify finally listens to them and updates their app to include this feature… for the iPad only.
