Genius, the Game Changer: Part 2

Sometime last week I was told to question the definiton of what a genius is and place it into my own description. After pondering the term for what felt like ever, I finally came to terms with settling that to me a person who is a genius is a "game changer", that they alter the way that we, members of society, percieve something in life. One week later, I still stand by my definition. I still like to think that different aspects in life--sports, music, art, television, culinary, basically everything--has their own game changer.
I had vaguely mentioned some people who could be considered game changers in the recent past--Babe Ruth, da Vinci, and Poe just to name a few. A game changer doesn't necessarily have to be a person though--sometimes the most brilliant ideas and concepts are thought of by a man of little knowledge. Although there are other things that could be considered brilliant and genius, I still like to think that it's easiest to relate it to a person. Sometimes, I like to think that even game changers have game changers, if that makes any sense.
To break that down a little: To me, music is a huge game changer in itself. It's made the adolescent's life easier to deal with, as well as allow everyone else to cope and express ourselves better, and enables another side of us to be shown, either the free spirit or the emotional that's hiding within all of us. Music is one of the things in the entertainment industry that has allowed human beings to better understand another person's feelings  as well as our own since as long as we can remember. There have been many game changers who have affected the sound of music--Bach and Mozart to name a few. A more modern group of people who have utterly changed the world of music would be The Beatles.
In the rare case that you haven't heard of The Beatles, they were a 60s British rock and roll band who has come to define the sense of rock genres all over the world. The Beatles have been mentioned by the editor of Rolling Stone, Robert Greenfield, as the Picasso of the music industry, "artists who broke through the constraints of their time period to come up with something that was unique and original.... in the form of popular music, no one will ever be more revolutionary, more creative and more distinctive". If interviewd, the majority of bands in the contemporary music world will voice that the British Invasion group has helped to define the music that they were attempting to put out, even if just a song was influenced by them. Many rising bands and solo artists have also made cover songs of The Beatles, like Aerosmith's "Come Together". I can even say that in modern times, the group still largely influences up-and-coming bands, like my friend in Brazil's band, Dunes.
There were radio stations that had forbid any music to be played before The Beatles, and they were one of the first bands to make music videos. As an opening act in the 1965 North American Tour, over 55,000 people showed up just to watch The Beatles perform.
If The Beatles are not considered a genius today, especially in the music industry, then I don't really know who is.
