I also wish that there was a thing where you perform the song and it tells you what you did wrong. But, for the most part, it's a good learning app.",

Just a picture right in the middle of the screen of a woman taking a bath with her elbow showing to make it look like her breast. And it was very realistic looking! I don't want my children having these images thrown in their face when I'm thinking they're just practicing piano songs!",
