DVDs 1-3 were played in the car, but the other DVDs are unused. Operation has been confirmed. Since there are many simple songs, it's for beginners.

I don't think you can speak English just by listening, but I feel like my ears were quite trained by playing it at home, in the car, and during spare time.
