I express my confusion over at the Jukebox

Not at all clear yet as to what I'm hearing when I listen to the new 2NE1 single. I express my confusion over at the Jukebox. Can't say I'm able to pick out the non-Western sounds the band are talking about in interviews* (trot, enka). Sounds like R&B-based dance-pop to me, but pushed into interestingly disparate melodic sections. But then, I'm not educated in Korean forms. Maybe you can help.
