Guys don't confuse Goa Trance making with Great Goa Trance making. There's a huge difference!
Everyone can make a Goa track with a soft studio and some practice, that doesn't mean that Goa is easy to be made, cause normally this track will sound mediocre at best.
It's not difficult to write rock music either if you know how to play guitar or even jazz. But I agree with Lemmiwinks here. Years later and from all the new schol goa artists I haven't heard anyone that come close to the quality, complexity and magic of Pleiadians, AP, Koxbox or Transwave.
Writing a catchy melody and add 2 or 3 layers on top is not such a big of deal. How are you gonna make all those elements flow together is!
For me the only kind of music that it's extremelly difficult (almost imposible) to write someone without talent is classical, since (most of the times) it's a multi-layer, highly complex music with an undescribable flow.
Besides classic everything else can easily or not so easily be made. Is it gonna be any good? I doubt that!
