The first one has that metallic sound that is a dead give away. First falsetto is quieter than the second one, and you can really hear as he increases the loudness of his voice, the metallic kicks in https://youtu.be/450p7goxZqg?t=1m27s https://youtu.be/450p7goxZqg?t=1m27s Second one has a "Cher moment" almost straight away, just after "wandering the desert a thousand days" the following "mmmm" has a glissando between two notes where we clearly hear the hard edge on what I assume is an auto tune lookahead. I don't actually know how they work, I just assume there's a lookahead for the next note approximation which makes glissandos sound funny. https://youtu.be/M8uPvX2te0I?t=31s https://youtu.be/M8uPvX2te0I?t=31s The last one I can't really fault for too much autotune, more a lack of it. The bridge is especially intense https://youtu.be/E0oyglKjbFQ?t=1m51s https://youtu.be/E0oyglKjbFQ?t=1m51s
