The invention works by detecting both physical and physiological reactions of a person listening to a song being played. When you enjoy a song, your body movements and facial expressions are markedly different from that when you listen to a song that you dislike. Apart from these indicators, there are some subtle signs like your heartrate, hand temperature that vary depending on how much you are enjoying a piece of music. These indicators and signs are detected to know whether you like a song or dislike it. For example, the invention looks for signs like bobbing of the head, snapping of the fingers, or tapping of a foot to conclude that you’re enjoying the music and automatically marks the music as your favourite.
