Bước 3: Thêm đoạn JavaScript sau vào giao diện hoặc là file JS của bạn. Ở đây mình tạo JS dạng Array để thêm danh sách các bài nhạc.

// Để thêm nhạc bạn sao chép và chỉnh sửa bên trong đoạn array như sau

//     artist: "Nghệ sĩ",
//     img: "Tên đường dẫn hình ảnh",
//     src: "Tên đường dẫn theo bài nhạc"
//   }
