Coldplay Expert said:The use of Auto-Tune on singers' and rappers' vocals was inescapable when this album came out. Jay addressed this situation in depth on “D.O.A. (Death of Auto-Tune)”.
In a clever bit of self-reference, Auto-Tune is actually put on the vocals here when Jay says the word “on”. Hov had used this trick before in the "Put On [Remix]", when he let his vocals be given the T-Pain treatment for a fleeting moment to highlight his overwhelming hatred of the device.
