You can't face another rendition of “Don't Stop Believin',” and the DJ always seems to ignore your request for Chaka Khan? Time to privatize your karaoke experience. Karaoke Melody, with two locations on Buford Highway, features individual rooms small enough for duets or large enough for a dozen. A staffer gives you an iPad from which you can choose hundreds of hits. Push a buzzer to order booze. Go ahead, bust out some Rebecca Black—there's no one to judge you.
