A media-playback device acquires a heart rate, selects a song with a first tempo, and initiates playback of the song. The song meets a set of qualification criteria and the first tempo is based on the heart rate, such as being equal to or less than the heart rate. The media-playback device also initiates playback of a binaural beat at a first frequency. Over a period of time, the binaural beat's first frequency is changed to a second frequency. Over the period of time, the first tempo can also be changed to a second tempo, where the second tempo is slower than the first tempo.
Claim CLM-00001. 1. A method for selecting and playing a song with a mobile device, the method comprising:
receiving a request from a user to play a song; receiving a context selection for a context for playback; detecting a user heart rate using a sensor and a light source of the mobile device, while the sensor and the light source are directed toward a part of the user's body; selecting a first song with a first tempo, wherein the first tempo is based on the user heart rate and the context selection; mixing a binaural beat with the first song; initiating playback of the first song, with the first tempo, and the binaural beat on the mobile device; and over a predetermined amount of time, reducing a frequency of the binaural beat.
Claim CLM-00014. 14. A system for selecting and playing a song, comprising:
a processing device; a database storing a plurality of songs, wherein the database is in communication with the processing device; a speaker in communication with the processing device; a heart rate-acquiring device in communication with the processing device; and a computer readable storage device storing data instructions which, when executed by the processing device, cause the system to:
receive a request from a user to play a song for a moment;receive a moment selection;acquire a user heart rate;select a first song with a first tempo, wherein the first tempo is based on the user heart rate and the moment selection;initiate playback of the first song with the first tempo on the mobile device;initiate playback of a second version of the first song, wherein the second version of the first song has a second tempo and the second tempo is slower than the first tempo;while initiating the playback of the second version of the first song, initiate cross-fading between the first version of the first song and the second version of the first song; andafter initiating cross fading, stop the playback of the first version of the first song.
Claim CLM-00019. 19. A non-transitory computer readable medium having instructions stored therein that, when executed by a processor within a mobile device, cause the mobile device to:
receive a request from a user to play a song for a moment; receive a moment selection; instruct a user to place a finger over a camera and a light source on the mobile device; illuminate the finger of the user; while the finger of the user is illuminated, acquire a user heart rate with the mobile device; after acquiring the user heart rate, indicate to the user to remove the finger from the camera and the light source; select a first song with a first tempo, wherein the first tempo is based on the user heart rate and the moment selection; initiate playback of the first song with the first tempo on the mobile device; receive a change tempo input; initiate playback of a second version of the first song, wherein the second version of the first song has a second tempo and the second tempo is slower than the first tempo; while initiating playback of the second version of the first song, initiate cross-fading between the first version of the first song and the second version of the first song; and after initiating cross-fading, stop playback of the first version of the first song.
