(not too sure if this is the official song, we're quite far away from 2014, so this might change)
2010 South Africa
2002 South Korea & Japan
What's your favourite of all the world cup's?
For me the 2010 world cup had the best songs compared to other years, and Waving flag was the best song of all.
I could go back further, but no one's going to watch them anyway, so there's no point; and the quality gets worse and worse each time anyway :P
