re: Mariah Carey meltdown on ABC (Video)

90% of major live performances the singers are lip syncing, it's not just pop music. When it's a rock group, for example, they pre-record their "live tracks" to make it sound more believeable. This is written into their contract and is non-negotiable. Producers and labels own artists now, the music industry has become a joke. They are also told what they can and can't wear on stage.
