popularity contest

I was wondering how popular this music is over in Europe. If I were to mention Massive to a group of college students or twenty somethings I suspect 1 in 10 would have a clue of what I am talking about. for groups like Zero 7 or Thieves I would think it is extremely small like 1 in 50 or something. Do other people in states agree with this notion? What type of popularity do these groups attain in Europe, specifically, Britain, Germany, France, Denmark (the important countries, :roll: ).

Thanks
