If you wait a certain time during the "press start" screen, they show the full Scorpion video where that music plays. It's the only part of the game where that music plays, though.

No.. It's not that music. I've watched that and it's totally different music in the full Scorpion video than what it is when they show it in the "MK History" thing.

In the real Scorpion video the music is techno and doesn't have any real drum sounds or anything.. Although I like techno. But in the MK History thing when they show it, fast, pumping metal is playing. Same music plays at the end of "MK History" when they show Quan Chi and Scorpions fight.
