I'm assuming these are reference tracks and not actual songs, correct?

I agree entirely with the notion that auto-tune is not singing, however, there's a big difference between using it for demo purposes, and using it in a track you intend to have on the radio.

Auto-tune is an incredible tool for reference tracks. When it comes down to it, you really don't want a singer referencing the song and hitting all the wrong notes, because then the eventual artist won't know what to do with it, THAT'S why auto-tune SHOULD be used. And that's primarily how it was used, until it blew into mainstream R&B/Hip-Hop in roughly 2005.

Anyways, my point is, auto-tune is a great tool depending on your intended use. Can it turn someone who can't sing into a singer? No, but it CAN be extremely useful when used appropriately.
