This CD is relatively old. One way you can tell is by looking at the disc itself. It's an 8cm mini CD. I recently heard on some internet radio that there's only one company left in Japan that can still produce mini CDs. Of course, I don't know if it's true, but it sounds plausible. The disc still comes in a full-size case (slim).
The songs are well sung and I don't feel anything negative about them, but I wouldn't say they're great either. Maybe they're just a bit dated, or maybe I just need to listen to them more.
