ah i understand what happened. the uploader uploaded the 2nd and 3rd track of the mix as one. as you can see in the related videos, DJ Vortex & Arpa's Dream - Incoming is track number 3 in that mix. in this video the uploader made an annotation that he messed up the song numbers. so the video you posted in the start post contains parts of DJ Darkzone - The Human Form and DJ Vortex & Arpa's Dream - Incoming.
