Well plenty of people listen to foreign music without knowing the language/culture. I listen to a lot of Chinese pop, both Mandarin and Cantonese, and I can't understand 95% of what they're saying, yet I still find it enjoyable to listen to.
As for modern pop music, yeah I guess from that standpoint Gangnam Style is a decent choice. Pop isn't my forte, but Gangnam Style seems like a good choice given other popular music nowadays....
this, I listen to a lot of japanese rock without the need to understand the lyrics, I guess so I can focus on the feeling of the music more
BTW, for everybody to know, PSY's label is pretty well known to bring american pop music styles and cycle it through korea as if its theirs, the beat of Gangnam style is no different to modern american pop
