If You Could Pick Only 1 Song to Introduce Someone to Epic, What Would you Pick?

I’ve been trying to come to a conclusion for this questions for so long and I’m still struggling. I’d want to pick one that’s incredible, shows the array of talent, but doesn’t spoil too much. I’d also want to pick something that wouldn’t require too much of an explanation for someone who has no clue what’s happening at that point in the musical. What would you pick?
