only thing I can think of is the fact Trance/Electronica music is a big thing in Germany, Amsterdam, Belgium, etc.
Trance is VERY hard to produce/mix because of the many sounds and many buildups and breakdowns...when they do hiphop its almost like taking a dog for a walk to them (well ok much more harder than that but it's significantly less harder to produce hiphop music than electronica imo).
+ I don't know for sure but I think the 808s, saw synths, plucks, bell noises, pads, snare rolls all derived from uses through electronica (DnB and breakbeats are a good example of drum patterns).
They got a lot of hi-tech stuff there too. They work their asses off and get exposed to a lots of people who have a thing for music..
we do too but yeah they're like on a whole new level.
