What's with the karaoke?!?

I really want to go to sleep, but for the past 3 hours there's been an insanely loud live band playing just a few meters from our window. The keyboard heavy music is accominied by the overzealous, out of key singing of a guy who probably thinks he sounds way better than he actually does. Every few songs he turns the mic over to a woman who's voice is less than harmoic, more along the lines of screaching. The crowd seems to love them though, maybe they are great performers? Or maybe its Asia's obsession with karaoke that's making them so popular!
