The soundtrack features 28 master tracks from the great decades of music, including 21 that are exclusive to Decades. For the first time, owners of Guitar Hero: On Tour or Decades will be able to stream over 50 songs from the two games using a local wireless connection. Guitar Hero: On Tour - Decades delivers the gameplay that players have come to expect and continues the ground-breaking on-the-go Guitar Hero experience.
