An application (APP) executing in a processor of a host device, may receive an electronic message (EM) that may include a handle for an address associated with the host device or a user of the host device, and a data payload that identifies content to be played back on a media device in communication (e.g., wirelessly) with the host device. An electronic messaging service may receive EM's addressed to the handle and may broadcast (e.g., wirelessly) the EM's. EM's received by the host device may be parsed by the APP to extract the handle and data payload. Data in the data payload may be used to search a content source for content to be communicated (e.g., wirelessly) for playback on the media device. Content specified in data payloads of EM's from one or more client devices (e.g., smartphones, tablets, pads) may be queued for playback on the media device.
