Two such scores that come instantly to mind are Vince DiCola's scores to Transformers: The Movie and Rocky IV. I wouldn't recommend Moroder because he stuff tends to sound a lot cheaper than DiCola's stuff. The same goes for the Europe song.
I can also recommend another synth driven 80s Power Anthem.
Oddly enough, while The Final Countdown is among my favorite songs of all time, I don't like Van Halen's Jump. It doesn't really... seem as powerful as Final Countdown is. Final Countdown just seems to have such an otherworldly, fantasy-like feel to it that really takes me away.
I've heard the samples on Rocky IV, but with the CD having a running time of 32 minutes, and the fact that it's an MAF (unlimited) release, I haven't really justified buying it yet. I've only heard Ivory Tower (the US version, I think) from Neverending Story. It's an okay tune, but I never really came back to it much.
Oh, and I found these as well. I want to buy/own the instrumental version SO BAD. ;_;
