@@sofianalbakheet6482 Firstly because his stuff is ghost produced or at least largely co-produced Benno De Goeij. Secondly armin was probably at one time a decent producer but technology moves quick and I would wager there are now thousands of no name bedroom producers who have way better chops than Armin. 140 Trance is pretty easy to produce in comparison to a lot of other electronic music genres.
It's actually hard to find a good copy of this mashup in general because, to the best of my knowledge there's no official release. So none of the copies out there are well mastered. As nice as this mashup is, this version of it on RU-vid leaves a lot to be desired.
