I don't have the numbers but I would be cautious there. Some US music is listened in other countries, but not all of it. Not everything is easily exportable.

Also there are local musicians popular in each country. And there are musicians from countries other than the US that are international but unknown in the US.

Anyway, Eurovision is quite irrelevant in Europe too :)

Edit... for native English speakers, consider this: there're songs in which the lyrics are more important than music. That kind of music is usually boring if you can't understand what they're saying.
