Should they have, like an international event similar to the olympics but with music?
 

Witnessed by Billions of people worldwide(Live Aid doesn't count) and Celebrating all different kinds of cultures. Like an even bigger WOMAD. What do you think?

It'd be unfair, Iron Maiden would riff slay every single polka band at the competition

Sounds kind of like Eurovision...except these days most sing in English rather than the country's native language. If it was like the Olympics but without the competition, I am all for it :)

First of you can't do a competition on music since you cannot truly measure it, just like there are people who enjoy Justin Bieber although I have no idea why and other who like Pink Floyd and Zeppelin.
