English lyrics appear at the bottom of the screen for karaoke sing-along. Analog tracks contain complete versions of the songs with guide vocals for practice. Digital tracks contain karaoke versions with only music and backing vocals. It is impossible to say for certain where the disc was manufactured, due to a total lack of mint markings. However, my best guess would be Kuraray. The width of the inner blank area appears to be the same, and there is a narrow ring which resembles the one normally seen on Kuraray products.
