Used to be fun until it failed me

Hello,

This app used to be fun and I easily spent over 50 dollars on it for hearts. Lately the game has been failing me before I even get the chance to play the song. I used a heart to replay the song so I dont lose the 36 LP but instead it failed me and took the heart. Hearts are NOT cheap. They are expensive and are taken seriously when playing this game. It has happened many times. Until they fix the problem my rating will stay the same and will not spend another penny on this game. Very disappointed, and not a satisfied costumer. Waste of money and time.
