Sounds like the most original person here is the person who made techno trance essential CD :)
It isn't hard to tell which CD's these artists all use. They do use the same kind of equipment (if any) when making these records. 1 good tune on a record with 3 shit ones they made in one day. Some do have nice ideas when putting the music together though, but not much of the loops/kicks/hats are made from scratch.

It would take too much time for them to make everything from scratch, and why waste time when this sells.
