Therefore, the Chinese patent with the publication number CN 104750685 A mentions a method of using the corresponding relationship between scenes and music to recommend different music in different scenes, but this method cannot automatically classify music according to various complex scenes. Manually establish the classification relationship; the Chinese patent with the publication number CN 104978983A also mentions the application scenario of optimizing the audio playback content according to the external environment, but this patent performs music classification and recommendation according to the label information in the music file. For most music files In general, there is no perfect label to mark the music style, so it is also necessary to manually set the music label, and if the music label is set incorrectly, it will have the opposite effect
