Yup - the new music is FANTASTIC. You might hear a snippet of the new leader music, but the new main theme is quite nice as well (Edited).
Ah, but where's the fun in that?
And since a lot of you are asking, this is the exact text on the Indonesia UA:
"Spice Islanders"
"The first 3 cities founded on continents other than where Indonesia started each provide 2 unique Luxury Resources (and can never be razed)."
I goofed and said first 2 cities in the video, but it's actually 3.
So 6 unique luxuries? That's awesome!
Edit: Also, could you confirm which wonders are unlocked by each policy tree?
