I looked this up on SoulseekQT. The Matt Darey Trance Mix came out on the Retrospective album (25 Years Of Matt Darey). It is 9:56 long. The track that is on Pure Trance 7 Extended (WEB) is also 9:56 long, so I guess these two are the same. However, the normal Pure Trance 7 release is just 4:03 long.
- Matt Darey - Retrospective (25 Years Of Matt Darey) [2019] - 9:56 long version
- Solarstone presents Pure Trance 7 Extended (WEB) [2019] - 9.56 long version
- Solarstone presents Pure Trance (Mixed By Kristina Sky, Solarstone & Lostly) (WEB) [2019] - 4:03 long version
Edit: I compared the one from the Retrospective and the one from Pure Trance 7, and to my ears, they both sound the same; the second is just significantly shorter.
