They came auto-tuned, because that's how they are on the song, I have the stuff to re-tune them, but there's no much point, seeing as my mixes won't get anywhere, if I knew they would, I'd spend time on my mixes, re-tuning things, compressing things etc.
But at the moment, I'm more focused on learning how to mix songs together, so I have a basic understanding on mixing and producing.
Thanks for all the comments, keep them coming!

I use Antares auto-tune myself, so I wouldn't have a clue how to work melodyne. (Self owned?)
