hi im a piano teacher and im using my daughters account and this is not good for kids it says on ads its totally free but it needs premium to learn your favorite songs my daughter loves this app but somehow she said that i need to give it 1 rating bc she cant learn her favorite songs and im really busy to teach her im teaching so many kids she is forcing me to buy it but we dont have much money So can you make the songs free? my daughter will appreciate it very much
