Lips is available in-stores now for the Xbox 360. For those who would rather a game that focuses on vocals as opposed to filling their living room with plastic instruments, Lips offers wireless, motion-sensitive microphones and the chance to sing from your own music collection - if you're interested in the title, check out our review!
