Libratone Beat is designed and developed to play music stored locally on your iOS device or your Mac/PC. If you primarily want to stream music from an Internet based service like Spotify, Pandora, Deezer etc. - we recommend using our AirPlay speakers Loop, Zipp, Live or Lounge.
Your excisting Libratone Beat could of course also be used in a wireless Apple AirPort Express setup. Read about Apple AirPort Express workaround here.
