This is a much better mix than the longer versions. Pretty much repeating techno beats, with Queen singing the Flash chrous, and some samples from the movie. Some other samples from the original version are included with added effects to the vocals. If you must listen to one version of this mix, this would be it.

I'm surprised this even got released, but this remix was supposedly popular in Germany. The first 50 seconds are a beat loop that kills any anticipation to hear the song. It features the typical dance mix backbeat, Queen singing the chorus parts, Ming's sample from the movie, and a lot of looping. It even manages to take out the best part of the song - Freddie's "just a man..." vocal solo.

Wow, they were able to turn the 6 1/2 minute Vanguard piece of crap into 7 1/2 minutes of worse crap. Features some more samples from the movie, some electronic sound effects, and a much faster dance backbeat.

At least this one sounds a bit different. This remix features a much different dance backbeat and looping. Much better than the Electro Mix, but still kind of crappy, and at over 7 minutes, who cares?

Again, more dance beat goodness (or should I say badness) with the occasional inclusion of Flash's Theme. This one is mostly an electronic looping instrumental.
