Maybe there was only one song at that time, and nothing else had been released. The album has a title song, which is premiered on the radio or on the Internet, and all kinds of music software are available when it is premiered, but of course, there are no other songs that are not broadcast. The songs of the album are available when they are released or when the album is listed, but sometimes some music software is not used for a while. Those songs are either released in the mainland or because of copyright prohibition, and many of them are like QQ music.
