I don't think it is "auto-tune".. do you idiots even know what auto tune means, yes the notes are probably Manually tuned but to suggest he sang and then let the computer match the pitches perfectly is insane, no self respecting band would ever do that. There is a distinct vocal effect used throughout the record to create the sound they wanted for this band. you can strongly hear this effect at the end of the song when Chris' voice is by itself. Sorry friends but if you think a band like this is using auto tune then you do not know what auto tune means.
Not all autotune sounds exactly like T-Pain there, hoss. There's a blend of auto-tune and pitch modulation. It's completely apparent.
Regardless, another killer track. Can't wait for the album.
