I signed up for premium and you guys charged me for all three instruments then when I canceled last month you guys continue to charge me despite the fact that I have canceled my subscription 5/15/18 So I decided to give app another chance. It has gotten terrible, the good songs are gone, used to have the actual artist for the premium songs and now it is just them singing the songs and its just not the same, the program doesn't pick up what I'm playing most the time so I get poor scores for songs
