This is the CD from the *Shoujo☆Kageki Revue Starlight ーThe LIVEー #1 revival* musical Blu-ray. It's the original cast recording of 7 selected songs from the Blu-ray.
The musical itself will also be translated and released sooner or later.
The reason the folder name is just "CD" is that I have it in my "Shoujo☆Kageki Revue Starlight ーThe LIVEー #1 revival" directory. You know, because this CD comes with the Blu-ray. You can name the folder whatever you want and put it wherever you want. I'm not the boss of you.
Edit: Accidentally the "e" in "Position Zero e!". I actually noticed and fixed this already, but the torrent file was out of date.
