"AB side" in the program "Do you listen to my music" means that the player's music works are divided into A side and B side, which is a concept of zoning. Side A and side B are like two sides of a tape, and each side carries different musical elements and styles. Players need to show different musical styles and creative abilities in different aspects of music works to attract the attention of the audience and judges. This assessment method aims to encourage players to try different music styles, expand their creative ability and make their music works more diverse and rich.
