When I heard the song I thought that I knew the band somehow, but it was really just from a cover by the Danish Cowpunk band, Disneyland After Dark.

I do not think you can say that anti-Americanism made Europeans stop listening to music from the US. Since WWII there has been US music all over the place. (I think that the Brits took over pop since the Beatles though).

But maybe the country and folk genres was under-represented. In Denmark it has always been a bit hard for people to dig the sentimentalist part of US culture and I think this might be true also for other Europeans. It does not really blend well with our demand for self-irony. The above mentioned band is a good example. They just had to blend in some silliness.
