specializta, I owe you an apology. I'm not a fan of Michael Buble but think he has a good if not particularly characteristic voice. I have only ever heard him sing swing or standards. I have none of his records. But I just looked up auto-tune on wikipedia, where I found this:-
Big band singer Michael Buble criticised Auto-Tune as making everyone sound the same – "like robots" – but admits he uses it when he records pop-oriented music.
So I apologise! I'm also pissed-off that it is now a "style". Pop is almost literally eating itself!
