Media is exchanged by the interaction between devices of an environment. A first device of a first user discovers existing devices within a proximity-based communication range of the first device that have media capable of being shared. As the first user encounters different people and places that have other devices, those other devices are discovered by the first device of the user. A list of available media is provided from the discovered devices to the first device where it is then displayed. The first user may then select a media item from the list to obtain it via sharing or purchase, have it bookmarked for future retrieval from the current source, or request playback of the media item such as by streaming or broadcast. The first device may provide information about capabilities and/or user profile information to the other devices to filter which media items are presented to the first device.
