Abstract: A computer server system associates one or more media items with a first segment of a first media item, the one or more media items selected based on current location information of a media device. The computer server system receives, from a media device, a request for a media item associated with the first media item, wherein the request includes a media segment identifier for the first segment of the first media item. In response to the request, the computer server system identifies the one or more media items associated with the first segment and provides the one or more media items to the media device.

Abstract: A system for supporting a user's repetitive motion activity operates to manage cadence-based playlists identifying one or more media content items having a tempo corresponding to a user's cadence. The cadence-based playlists can be categorized by different tempi or tempo ranges that cover all likely cadences during the user's activities. A media-playback device is provided to acquire a user's cadence and retrieve a cadence-based playlist associated with a tempo or a tempo range corresponding to the cadence.

Abstract: Systems, devices, apparatuses, components, methods, and techniques for generating and playing a selectable content depth media program are provided. Media content items are edited to produce selectable depth media segments which are assembled into selectable depth media programs. A media-playback device is configured to navigate and play the selectable depth media program through interaction by a listening user. The user selects the desired content depth for each media segment.

Abstract: A system for playing media content items operates to provide smooth transitions between the media content items to continuously support a user's repetitive motion activity. The system can generate crossfade data containing information for transitions between media content items. The mix-in and mix-out points for the transitions are calculated to eliminate one or more portions of media content items that have lower musical energy than a majority portion of the items, and to maintain substantially consistent and/or stable musical energy (e.g., audio power or sound power) throughout the media content items including transitions therebetween.

Abstract: At a client computer, a web browser is connected to a local web server. The local web server is coupled with a local utility executing on the client computer that is distinct from the web browser. The web browser sends, to the local web server via a first communications channel, a first open-ended message that does not require a return message. The local web server waits until the local utility determines there is information to be provided to the web browser and sends, via the first communications channel, a first return message responsive to the first open-ended message. The web browser, in response to and upon receiving the first return message responsive, maintains communication with the local web server by sending, using a second communications channel distinct from the first communications channel, a second open-ended message that does not require a return message to the local web server.

Abstract: A first electronic device, while a first media content item of a first type is playing back on a second electronic device, detects a user input selecting a second media content item. In response to the user input, the electronic device determines a type of media content item of the selected second media content item. In accordance with a determination that the second media content item is of the first type of media content item, the first electronic device generates a media control request for controlling playback of the second media content item at the second electronic device, and in accordance with a determination that the second media content item is of a second type of media content item, the first electronic device generates a media control request for controlling playback of the second media content item at a third electronic device that is distinct from the second electronic device.
