I did this four years ago but never finished it. So, here. Some of it, anyway.

Uruguay: El Cuarteto De Nos - Yendo A La Casa De Damián (from the album Raro (2006))
South Korea: Psy - Korea (I chose this because I know it was made for the Olympics but it works for the World Cup all the same! Korea Fighting!)
Greece: Koza Mostra - Alcohol is Free
Japan:
Switzerlad: Sebalter - Hunter of Stars
Bosnia & Herzegovina: Dino Merlin - Burek (from the album Burek (2004)) or Grupa Regina - Zvacu te pile moje (from the album VRIJEME JE (2009)) or IDK THERES SO MANY GOOD SONGS
