Fun but frustrating

I like this game a lot but there are so many ads and its hard to get smoola to buy new songs. Also, the daily challenge frustrates me to no end because I will play the song completely right and get a perfect score, only to find out the person in number one has 500+ points more than I do when we both got perfect.
