!! This album should be "shuffle play". !! The album is a single piece of music with all of the tracks connected to each other. However, it is not necessary to play the tracks in order starting from the first track, by playing the songs in a random order. The composition of the songs changes every time you listen to them. We hope you will enjoy listening to it over and over again, and that you will enjoy the music as it changes each time you listen to it.
