I used this when I was taking piano lessons. I haven't listened to all the songs, but I was able to play them on a CD player, so I think they should all play. Since a child used it, there may be some minor scratches or stains. The CDs themselves seem to be in relatively good condition. A fun piano CD for children, with a complete song list. - Product Name: Nakayoshi Piano 1 - Brand: YAMAHA - Genre: Kids/Family - Price: 1200 yen - Country of Manufacture: Japan Thank you for looking.
