I bring you the two songs I was absolutely bombarded with during my time abroad.
The first is a shit video, because it was the official song for FIFA, Shakira's Waka Waka (This Time For Africa). Just play it and work on something else. Annoyingly catchy. "Waka waka," to the best of my knowledge, means "do it." I heard this a bunch in Sweden since the World Cup was on, but needless to say, you can imagine how much I heard it in Africa!!
This I heard mostly at night in bars and clubs, completely different...fun video. Doesn't seem like something you would hear everywhere you go, but I did. Go figure.
