First thing is the beat, not too fast not too slow, it catches you in a second and it doesn't let you go anymore. It goes on and on and on... then a bass begin to pulse very low, you start to feel strange, a voice repeats the same thing again and again, like an obsessive thought and a warm wave rises from nothing...
It's time for a merciless crescendo, every element melts with each other, the beat stops for a while leaving you breathless... when it gets back you have finally lost control and you float helpless inside pleasure.
That's what I call an Errotick track.
