...As I said before:
How is this overproduced? Is it auto-tuned? Probably, but EVERY SINGLE LINKIN PARK SONG SINCE HYBRID THEORY (except for MAYBE The Messenger) has had auto-tuned vocals. It's an industry standard. It has been for a decade and a half. In terms of the use of more OBVIOUS pitch correction/vocal effects, Out of Ashes' vocals aren't any more "over-produced" than the vocals on the last two Linkin Park albums (although there are certainly more layered harmonies than the typical LP song has), and this STP stuff is SIGNIFICANTLY more raw-sounding than any of those 3 records.
I'm honestly BAFFLED by this. STP is a pretty straightforward rock band, no keyboards, no DJ, no need for any crazy electronic vocal effects. Meanwhile, Linkin Park has been employing the use of vocoders, flanger effects, tons of echo, vocal scratching/"chopping," etc. for the last several years...but somehow the vocals on LP records hardly get criticized at all, yet THIS is "overproduced?" Do people seriously think Chester should sound like he's singing in the fucking Ramones when he's not on a Linkin Park record or what?
