Yea...using the look in teh meaters if they bounce into the "red" alittle, maybe jsut throw most of that out and go by my own years, spend more time during the mixdown etc?
Just turn any tracks that are peaking down or just turn the whole mix down. Use a limiter to make it louder after that. Hitting the red introduces distortion but not that sweet saturation that analogue desks introduce and it can sound different depending on the end listener's DAC. TBH, hitting the red slightly is rarely going to make a discernable difference but there's no benefit to it.
Also, almost all modern digital music peaks now but not because they peaked the masters (they almost certainly would have left AT LEAST -0.3db head room, likely more), it's because of ISP's (https://www.swiftmastering.co.uk/inter-sample-peaks-isps/) which are introduced when compressing WAVs.
