Abstract: Example embodiments relate to methods and systems for playback of adaptive music corresponding to an athletic activity. A user input is received from a user selecting an existing song for audible playback to the user, the song comprising a plurality of audio layers including at least a first layer, a second layer, and a third layer. Augmented playback of the existing song to the user is initiated by audibly providing the first layer but not the second layer. Physical activity information derived from a sensor corresponding to a real-time physical activity level of a user is received. If the physical activity level of the user is above a first activity level threshold, the augmented playback of the existing song is continued by audibly providing the first layer and the second layer to the user.

Abstract: Example embodiments relate to systems, methods, apparatuses, and computer readable media relating to a user interface, that may for example, initiate transmission of a stream of audio data comprising a plurality of audio tracks from a music streaming service, and receive athletic activity data relating to a performance of an athletic activity by a user during an activity time period that includes a plurality of time intervals. For each of the plurality of time intervals, an athletic activity level is determined from the athletic activity data, a target audio track intensity corresponding to the athletic activity level is determined, and a playback of a streamed audio track corresponding to the target audio track intensity is initiated.
