Literature Review and K-pop

Listening to music has always been a given whatever I'm doing, whether writing a report, reading a book, or thinking of what to do next.

Depending on my mood for a particular day, the playlist would differ: classic, praise and worship, country,  acoustic or OPM. Since I left my netbook which contains that different type of music at home, my choices have been cut down into two major categories: pop (English) or K-pop.

At first, I intentionally listen to Korean songs while reading documents which are written in English, and then listen to English or OPM songs while studying Korean Language. I did this because I thought by doing so I'm able to concentrate better on what I'm reading or studying.

Nowadays, it does not work as well as it used to. While reading research articles, a word or phrase in the Korean song I'm listening to would catch my attention and without realizing it, I'm already looking for that particular phrase, learning how to write it, looking at the context with which it was used, or worst looking up the translation for the whole song.

Should I stick to instrumental or classical music instead?
