A user initiates a synchronized playback by sending a request to one or more multimedia devices across a network. The user selects a multimedia sample and a start time. When the request is received by other multimedia devices on the network it can be accepted or denied. If the recipient accepts, the multimedia sample can be downloaded or cached before or streamed at the time of play. Many can enjoy listening to the same multimedia sample even using headphones. This enables a group to enjoy synchronized movement without requiring a sound system other than headphones."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for synchronized playout of music on several personal digital music players","description":"Devices, systems and methods are disclosed which relate to a plurality of multimedia devices operating on a common time base having the ability to synchronize playback of a multimedia sample.
