I was originally going to rate this game 3 stars because there are some good parts & some bad. It started good, the selection of music was okay but that's mostly at the top of the list. It gets less varied as you scroll on. You start with 3/4 free songs then you have to watch an ad or use gems to unlock other songs. The volume for some songs is balanced, but for others it goes up & down or it's very low & barely audible. I had almost 1000 gems & somehow they reset to 0, & I don't wanna play now.
