Non-English/Korean/Japanese lyrics?
K-Pop is somewhat infamous for its occasional use of English lyrics in songs. In addition many songs are translated to or natively Japanese. It's rare however to see non-English, Japanese or Korean lyrics in songs. How many can you think about?
Being the most global K-Pop group it comes as no surprise that I can instantly name a few lines containing lyrics like these from 2NE1.
Go Away (Spanish)
"아녕, goodbye, adios.
Let's Go Party (French & Tagalog)
"on y va faire la fête"
+
"Punta tayo sa fiesta"
I initially thought that RANIA sang "bitte, bitte kommen" during the pre-chorus of Style, but it turns out that they weren't, and thankfully so.
Can you think of any other instances? Perhaps from your lesser favs?
