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. ## Claims ### Claim 1 A computing device comprising: at least one processing device; and at least one computer readable data storage device storing instructions that, when executed by the at least one processing device, cause a media-playback device to: acquire a heart rate; select at least one media content item with a first tempo, wherein the at least one media content item meets a set of qualification criteria; and wherein the first tempo is based on the heart rate; initiate playback of the at least one media content item; over a period of time during the playback of the at least one media content item, change the first tempo to a second tempo, the second tempo being slower than the first tempo; initiate playback of a binaural beat at a first frequency during the playback of the at least one media content item; and over the period of time during the playback of the at least one media content item, change the binaural beat to a second frequency. ### Claim 2 (depends on 1) The computing device of claim 1, wherein playback of the at least one media content item continues for at least 15 minutes. ### Claim 3 (depends on 2) The computing device of claim 2, wherein the media-playback device acquires the heart rate. ### Claim 4 (depends on 2) The computing device of claim 2, wherein the media-playback device acquires the heart rate from an external device. ### Claim 5 (depends on 1) The computing device of claim 1, wherein the set of qualification criteria includes: a major key and an absence of lyrics. ### Claim 6 (depends on 5) The computing device of claim 5, further comprising instructions that, when executed by the at least one processing device, cause the media-playback device to: receive an environment selection; and based on the environment selection, initiate playback of white noise. ### Claim 7 (depends on 6) The computing device of claim 6, wherein the first frequency is about 12 Hertz (Hz) and wherein the second frequency is about 7 Hz. ### Claim 8 (depends on 1) The computing device of claim 1, wherein the period of time is at least about 90 seconds. ### Claim 9 (depends on 1) The computing device of claim 1, wherein the period of time is at least about 5 minutes. ### Claim 10 A method for selecting and playing a song, the method comprising: using a computing device: acquiring a heart rate; acquiring a moment selection; selecting at least one song with a first tempo, wherein the at least one song meets a set of qualification criteria; and wherein the first tempo is based on the heart rate and the moment selection; initiating playback of the at least one song; initiating playback of a binaural beat at a first frequency at least partially during the playback of the at least one song; and causing the binaural beat to change to a second frequency during the playback of the at least one song. ### Claim 11 (depends on 10) The method of claim 10, further comprising: during the playback of the at least one song, decreasing continuously the first tempo to a second tempo, wherein playback of the at least one song continues for at least 15 minutes. ### Claim 12 (depends on 11) The method of claim 11, wherein the set of qualification criteria includes: a major key and an absence of lyrics. ### Claim 13 (depends on 12) The method of claim 12, wherein the first frequency is about 12 Hertz (Hz) and wherein the second frequency is about 7 Hz. ### Claim 14 (depends on 10) The method of claim 10, wherein the first tempo matches the heart rate. ### Claim 15 (depends on 14) The method of claim 14, wherein the set of qualification criteria includes: a major key and an absence of lyrics in the song. ### Claim 16 A media server comprising: a database storing at least a plurality of songs that meet a set of qualification criteria, the set of qualification criteria including: a major key and an absence of lyrics; at least one processing device in data communication with the database; and at least one computer readable storage device storing data instructions which, when executed by the at least one processing device, cause the media server to: acquire a heart rate; select a song from the plurality of songs, wherein the song has a first tempo and wherein the first tempo is based on the heart rate; initiate playback of the song; initiate playback of a binaural beat at a first frequency during the playback of the song; and over a period of time during the playback of the song, change the binaural beat to a second frequency. ### Claim 17 (depends on 16) The media server of claim 16, wherein the instructions further cause the media server to: over the period of time during the playback of the song, change the first tempo to a second tempo, the second tempo being slower than the first tempo; receive a moment selection; based on the moment selection, initiate playback of white noise in addition to the playback of the song; wherein playback of the song continues for at least 10 minutes; and wherein a media-playback device acquires the heart rate, the media-playback device being in communication with the media server. ### Claim 18 (depends on 17) The media server of claim 17, wherein the first frequency is about 12 Hertz (Hz) and wherein the second frequency is about 7 Hz; and wherein the period of time is at least about 90 seconds. ### Claim 19 (depends on 18) The media server of claim 18, wherein the first tempo matches the heart rate. ### Claim 20 (depends on 19) The media server of claim 19, wherein the song has a first duration; and wherein a second song is selected for playback when the first duration is less than 10 minutes.
