kpop1-6, Exercise 2: English in the charts

Model answer:

English names in the top fifty: 14 (1995), 17 (2000), 31 (2005), 41 (2010), after none in 1990 - a steady rise.
English in song titles: 8% (1995), 30% (2000), 18% (2005), 44% (2010) - overall higher, but not smooth, because it dips in 2005.
The title figures should not be read as a smooth rise because the article gives no explanation for the dip; it could be a real change, a change in which songs charted, or a difference in how the counts were made.

Two reasons the article gives (any two): the government stopped censoring English lyrics after the 1997 financial crisis, and Korea had a boom in English; Korean-American or US-educated performers use their English fluency; companies want to enter other Asian markets and then the West; bands use English names to be marketed to a wider audience.
