Considering Beethoven's 9th is over one hour long, it may be considered an album in modern terms, so I think asking for one song is cheatingInverse Skies said:Lol, as I said to Top Hat Tim who suggested the Beatles, technically I was looking for one song rather than an artist... but your answer is still a very good one because yes... while it is ahem... Eminem... he did influence a lot of people with his work...S.H.A.R.P. said:As much as I hate to say it, I would have to mention the works of the rapper Eminem. Eminem popularised an entire genre of music to the western audience generally shunned by mainstream people. He has paved the way for countless of young white kids to become what is often referred to as 'wiggers'. I think he is responsible for making rap to be one of the most popular genres to day, and making it easy for countless of uninspired rappers to sell countless of their uninspired albums with their undistinguishable uninspired songs to countless of uninspired kids and other young people (sorry, I just had to emphasise it slightly).
'Thanks' to him, lots of people consider money, drugs and 'hoes' to be the important things in life, and that woman are unintelligible products of desire, eagerly willing to pull down their pants and wiggle their butts before the camera while being slapped with big bags o' money (despite that his own albums were far better then the hellspawn he has opened the gates for). Besides the aforementioned, there are countless of other stuff he has paved the way for, mostly - if not all - very undesirable.
Well, you didn't say a positive contribution to culture!
In the light of scape's answer, what about Happy Birthday to You [http://en.allexperts.com/e/h/ha/happy_birthday_to_you.htm]? That's not only song at childhood, but it is song every year! Say life expectancy is about 80 years, surely you won't sing the ABC song 80 times!
Oh and might I add that I take into account the version of other country's, since both the alphabet song and happy birthday have their very similar counterpart in other languages.
