I'm actually really enjoying the game now after the second piece, but kept missing certain notes on the third piece. I was suspicious about those notes so did a google, and apparently a lot of people have issues with it, and one person said to just turn the sound off. Tried it and got considerably better scores, and then went one further and played random music from my phone and got even better. Convinced now that those specific notes are not on time to the game mechanics in the game!
