Abstract: A system and methods for acquiring cadence and selecting a song version based on the acquired cadence are disclosed. If the system detects a new cadence, then a new song version that corresponds to the new cadence can be played. The new song version playback can start in a corresponding position as the location of playback in a currently-playing song version. Each related song version shares one or more characteristics, such as melody, but is different in at least one characteristic, such as tempo.

Abstract: A system operates to manage accessibility of media content items based on a user's performance of a repetitive motion activity. The system can generate rule data based on a rule designed to permit access to certain media content items. The rule data can include information about various conditions to be satisfied to make the media content items accessible for playback. Such conditions can be associated with a user's performance or status of a repetitive motion activity.

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: A system and method for playback of media content, for example music, video, or other media content. A media device having a media playback application and including a touch-sensitive user interface can be adapted to display a visual array of media options, for example as a grid or list of card elements. Each media option can be associated with one or more media content items that can be streamed to and/or played on the device. The system can determine a selected card element, or media options that are proximate to a selected point or region of the visual array, and play or crossfade media content as appropriate. In accordance with various embodiments, additional features can be provided that improve user interaction, for example the use of audible notifications, media caching, or touch menus.

Abstract: A system for multi-track playback of media content includes: a media device; a user interface, provided at the media device, which displays a visual array of media options, a playback logic, provided within the media device, which is configured so that, while a selected point or region is determined by the user interface as being moved in response to user input, within the visual array of media options, the system determines media options that are proximate to the selected point or region, and adjusts playback parameters for corresponding media content items, by crossfading or otherwise combining playback to reflect the media options relative distances from the selected point or region; and a tempo logic, provided within the media device, which is configured to provide or receive a selected tempo and provide the one or more media content items associated with the selected tempo.

Abstract: Systems, devices, apparatuses, components, methods, and techniques for cadence determination and media content selection are provided. An example media-playback device comprises a media-output device that plays media content items, a cadence-acquiring device, and a cadence-based media content selection engine. The cadence-acquiring device includes an accelerometer and a cadence-determination engine configured to determine a cadence based on acceleration data captured by the accelerometer. The cadence-based media content selection engine is configured to identify a media content item based on the cadence determined by the cadence-determining engine and cause the media-output device to playback the identified media content item.

Abstract: Systems, devices, apparatuses, components, methods, and techniques for identifying media content for playback during a repetitive motion activity are provided. An example media-playback device includes a media-output device that plays media content items and a repetitive-motion activity content identification engine. The repetitive-motion activity content identification engine is configured to: review media content items to identify the media content items that are conducive to performing repetitive-motion activities; and select certain media content items from the media content items, the certain media content items being conducive to performing the repetitive-motion activities.

Abstract: A media system includes: media-playback device including: a media-output device that plays media content items; and a tempo control engine configured to: receive a selection of a desired tempo; and suggest additional media content associated with the desired tempo.

Abstract: A system and methods for acquiring cadence and selecting a song version based on the acquired cadence are disclosed. If the system detects a new cadence, then a new song version that corresponds to the new cadence can be played. The new song version playback can start in a corresponding position as the location of playback in a currently-playing song version. Each related song version shares one or more characteristics, such as melody, but is different in at least one characteristic, such as tempo.

Abstract: Systems, apparatuses, components, methods, and techniques for acquiring a cadence and selecting one song version from more than one versions of a song are disclosed. An example system acquires a cadence and selects one of a plurality of song versions that has a tempo matching the acquired cadence. Each song version shares at least one characteristic, such as a melody, and each song version is different from each of the other song versions in at least one characteristic, such as tempo. The different song versions can be based on different musical compositions composed for different tempos.
