I would really like to see them use an Arcade Fire song. Ready to Start is new and hot and happening, while being somewhat applicable to the introduction of the starting lineup. It's got the right energy and it could even be looked at as being part of introducing an entirely new era.
Of course the subject matter of the lyrics, aside from the title, don't quite work, but they could use the last minute of the song for the video, and then loop the instrumental part at the beginning of the song. Or they could just commission the band to record a suitable version, and make a big deal about how the proceeds are going to Haiti, which the band would have no problem with - having pledged 1 million of their touring earnings. Would it be so hard to do something that speaks to local culture, while straying away from the usual corporate crossover promotions?
