Kpop has become extremely popular in recent years. Most Kpop bands already have a massive audience in South-Korea, and are looking towards western audiences to expand. This might be why some Kpop bands started to use English words and phrases in their songs. Does this help them become popular in Europe and North America?

1) Does the use of English words and phrases help appeal to western audiences?
2) Sometimes the English words or phrases used by Kpop artists is rather mediocre or bad, does this affect how western audiences appriciate a song?
3) Can you find examples of Dutch songs with English words/phrases and can you compare this to Kpop songs that do the same? What are the main differences and/or similarities?
