Oh no! Someone hacked the Beatmania machine and put a rickroll in all the songs. All of my favorite song levels are ruined now. There was also this note left on the side of the machine. What could this all mean? Is someone trying to hide something? You must uncover the culprit of this heinous crime!

Whew! I've finally managed to get rid of that annoying rickroll. Now I can actually hear the songs correctly.

Hint #1: If you have terrible music taste and don't know these songs, there are a lot of apps out in the world which can help you figure out what the songs are.
