“Sexy Clap” is a perfectly reasonable thing to call a K-pop song if you don’t know American English slang.
I’ve been meaning to post this for a while. Back in August, Pitchfork put together its 20 Essential K-Pop Songs (with the usual Pitchfork sense of self importance, since the notion that any K-pop is essential is pretty silly). I don’t love every one of their selections, but they hit on some great stuff, and their approach serves as a reminder that even if it’s manufactured, it’s creative and innovative too. Worth a look and listen.
