Yeah it seems from the page that it has mixes of electro, underground, trance, not just trance.
Since the past few years, most Eurodance and Trance DJs have switched to electro, but still claim themselves or their compilations as trance/euro mixes. Eg the Euromix series by Tony Monaco no longer features any eurodance since the 2007 release and when you get a new DJ Tiesto album, it no longer features any trance, even though he was a long time trance artist and mixer.
