Coldplay's "Viva la vida" is a great song - but why ?

It is simple and thus many people on Youtube play it and sing it and even teach tutorials how to play it. Why is this ?

1) The hammering sound is made of very few accords and thus very simple and this actually makes it powerful, in fact it carries the song.

2) These few accords are kinda brutal.

3) They talk to the archaic, the most ancient part of our brain, to our earliest instincts: It talks about a stormy world where we withstand the winds that are blowing our face. The hammering is actually showing both things at the same time: The strength of the storm and the repetition of the beat is showing the resistance of us standing in this storm not letting us being blown away but encounter the storm. Well, that's just my interpretation.

4) The artists voice in this song is kinda understated, maybe by intention, maybe by accident, maybe for other reaons, but the lyrics hammer out the same message that the archaic music tells:

(Free repetition:) "I was sent to earth, the first man, the one who came to rule the world. But I didn't do well as a king, not even as a prophet, I overestimated my powers and was displaced from my post by some higher forces."

Actually the band name Coldplay fits into this scenario pretty well: "An unimotional (cold) description of the protagonist of the song being set into this world and describing his way of life from a distant point of view.

There is an artist named xcaroolyn (search for her on youtube) who intensifies (interprets) the message of the song even more than Coldplay themselves do. And I think she is totally right about the stricter accentuation of the hammering sound, so I recommend listening to her interpretation of Viva la Vida on Youtube.
