I practically cried because all those songs were amazing. While listening, I thought "what will become of video game music in the archives of human history?"
Beethoven, Bach, Mozart, etc all made their mark in the history of music as pioneers of musical advancement in their time. The piano was just invented when they all became famous, so they had to learn the instrument through many performances. With that comes skill and knowledge of musical genius rarely seen today, when anyone can make "music" with just a touch of a button.
