The only places I found were old-fashioned public karaoke where you sing in front of the whole bar. How is this still a thing? That’s not karaoke — that’s open mic night.
Another fun discovery via powRSS, but unfortunately, I have to disagree. The best karaoke is when you get a whole bar a little tipsy and everyone gets on the same wavelength of having fun and not caring if you sound good and everyone ends up singing along.
