The seventh official song by the second singer of AI Singer Label & Media "GEMVOX" is "HEARTBEAT" by up-and-coming creator YMSR. It is a lo-fi, chill, one-way love song that expresses the nighttime in the city, making use of the clear voice quality of AI singer, Shiraki Jasper. Set to a downtempo track, it sings of the delicate heart of a man who coolly burns with love.
