In Korea, karaoke is done in private rooms or noraebang (노래방). It literally means "song room" and it's a place for friends to gather and have a good time in private. And depending on your skill level it's best kept in private!
Summation: I'm feeling like Bill Murray from that scene in Lost in Translation. A bit of a push but innocent fun... no Roxy Music here though.
FYI In Japan, noraebangs are called "karaoke box" or "kbox."
