The English Rock band "Muse" wrote the song "Survival" as the official song of this global event. The song is expected to be heard during the beggining of the Olympic Games in London, when the athletes enter in the stadium and during the awarding medals.
Finally, a normal song will be heard in a such event, I got tired of listening to all these pop craps. :D
Feel free to judge the song.
PS. I was expecting Iron Maiden to take care about the official song of Olympic Games :D
