This is a lot of fun and I'm enjoying it, and I greatly appreciate your efforts in putting this together, but if I might add a bit of friendly feedback it does irk me a bit that the charts don't always follow the same melodical instrument and randomly switch between them, or occaisionally to percussion or vocals. Like in "Now's Your Chance to Be A," the chart starts on the melody but switches to vocals and then to a different instrument halfway through. It makes the charts hard to follow as a result and I end up doing a lot worse on them because of it.
