On a serious note, here in the middle of America, you don't hear Spanish language music unless you listen to the Spanish language stations & channels.  I generally do not.  I know of people like, say, Christina Aguilera, because the media is plastered with them.  The media -I swear- is not plastered with Enrique Iglesias.  

Miami hardly representative of America.  But there appears to be widespread knowledge of this guy throughout Europe.
