Chord Crush pretty disorganized

I had no idea this thing existed, and it was pretty fun for the first twenty minutes. Unfortunately I’ve done many of the same exact questions for the same exact song at least 1/3 to 1/2 of the time. Another 1/4 of the time is spent slowly shuffling through questions with no (valid) YouTube video attached. I realize maybe Chord Crush isn’t very high priority, but it’s currently kind of a waste of time when I get the same The Chicks song three or four times in a row (artificially boosting my score, making questions harder, and wasting my time).
