Well, yes, it was a bit irreverent to classify "Gangnam Style" as a classic, but it clearly is (or more accurately, it will be). At least people have heard it, which is more that can be said for real classics.
Well, these two Korean girls do it justice, and make an acoustic version that is actually (dare I say it?) "listenable". Of course, it doesn't hurt that the girls in question are, ehem, "watchable", does it?
Let me know what you think in the comments!
