You know why that song was played.
Anyway, this is how I think it shakes out for the US in the Knockout Stage provided they finish first or second in Group D or are one of the top eight 3rd place finishers:
1. If USA wins Group D
Will play 3rd place in:
Group B (Canada, UEFA Path A winner, Qatar, Switzerland)
Group E (Germany, Curacao, Ivory Coast, Ecuador)
Group F (Netherlands, Japan, UEFA Path B winner, Tunisia)
Group I (France, Senegal, IC Path 2 winner, Norway)
Group J (Argentina, Algeria, Austria, Jordan)
2. If USA places 2nd in Group D
Will play Runner-Up in:
Group G (Belgium, Egypt, Iran, New Zealand)
3. If USA places 3rd in Group D (and is one of the top eight 3rd-place teams):
Will play Winner in:
Group K (Portugal, IC Path 1 winner, Uzbekistan, Colombia)
Group I (France, Senegal, IC Path 2 winner, Norway)
Group E (Germany, Curacao, Ivory Coast, Ecuador
