In Swedish, this key change is generally called a "schlagerhöjning", where "schlager" [2] is the broad genre word for the type of songs that compete in the Eurovision. The term is old, obviously there's a rather wide genre spread these days but it used to be more same-same.
Edit: added a "Swedish" above, I did not realize that the chart only lists Swedish music, saw another comment mention this. Very weird of me.

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.
Look at the Billboard (or equivalent) charts for Germany, France, Argentina, or any other non-Anglo country; maybe 10% of the entries are English language or from American artists.
Eurovision is hugely popular and continuously and commercially successful outside of the charts world.
