Abstract
Disclosed is a system and application for digital media that allows users to share a media playlist and synchronize playing for all connected users. The user browses their device for media files to create a playlist, and then hosts the playlist over an existing local area network or creates a Wi-Fi hotspot. The playlist may be encrypted to provide a form of digital rights management. Other users are then prompted to download the playlist and send the host a calculated playback delay. Once all users have completed downloading the playlist the hosting user is prompted to press play, pushing timing information that takes into account the largest delay to all connected users via the active local area network, resulting in all devices playing the media in synchronicity for the duration of the playlist. Additional users may opt in during playback and use the timing information to synchronize their devices' playback.
