I have a premium account and would love my wife to also enjoy the same experience. We live check to check and would prefer to share one account. Is it possible and how do I go about doing that. Thanks guys.
No, you can't listen to music with multiple devices at the same time.
You can have offline playlists on up to 3 devices at once. You can use the offline mode to listen to offline playlists on one device and be online on the other one, but you can't listen to music online with two devices at once.
