I'm sure your students are excellent, but I can barely watch The Voice and some other franchise singing contests, except maybe in the live rounds, but they've lost me by then, because of the horrible autotune they use. Actually the The Voice USA has gotten a little better in that regard as far as obviousness, but The Voice in some other countries, like Germany and Norway, which I viewed recently, are pretty bad with it. I mainly watch singing competitions in the Philippines where they don't use it at all.
