Kurohata said Ordinary World would be good, and I agree. The only place I've heard that song is DDR Max, and it's always fun to dance to. In fact, a lot of songs on Max would be great for a techno vid; they're all mostly upbeat techno tracks.
This site has all the mixes, songs, and artists. I don't want to seem like I'm copying ErMaC, but he
did get me into the Space Brothers. They have some really amazing songs. My personal fav is Forgiven (I Feel Your Love). I've been trying to come up with ideas for a vid for that one, but I haven't yet. As always, ATB is still the king of trance in my eyes, so you could try some of his stuff too.
