What mix comes on at about 43:00 in Trance Nation 4 CD 1? There're some lyrics like "Open your heart to love" and I read a tracklist that says that it's a Darude rmx, but Darude's all seem to have the little riff from Sandstorm, so I seriously doubt it's a Darude mix. Any ideas?

Yep, it isn't the Darude Remix it's the "open your arms" vocal mix made by Armin himself. Just a fault on the cover I think or
