And that's a problem, why? The same is true of Coronation Street's theme tune (which hasn't changed since it launched in 1960), right? Besides, if music being dated was a problem, nobody would listen to stuff not currently in the charts. It doesn't matter if it isn't up to date, what matters is that the music fits in with the rest of the soundtrack - like the main Gladiators theme and Another One Bites The Dust. And that's the main complaint about the new tunes from what I've seen, people are complaining that they don't fit.

Of course, even if they did keep the original themes, only four out of seven could've been used anyway, as the Atlaspheres, Danger Zone, and Swingshot events haven't been used.
