Just thought I'd put down this wonderful discussion I found in an interview Big Bang had with Washington Post.  (citing bc I'm cool)

“Actually, I don’t know why they call Korean music ‘K-pop,’” Seungri said. “Good music is good music, so if you are going to be doing good music, then they are going to be listening to our music.”

G-Dragon chimed in. “We are Korean, so obviously they call our music K-pop. But we never thought of our music as K-pop. Our music is just our music.”

“It’s like this,” added T.O.P. “You don’t divide pop music by who’s doing it. We don’t say, for instance, ‘white pop’ when white people make music.”
