By doing that your crushing the song dynamics. No dimensions in the song. Just a wall of loud noise. and your happy with that? Care to post some songs so I can hear what "double mastering" from you sounds like?
i'll send you something when on pc
but i make all types of stuff for myself, i dont double master everything , just the stuff that i feel needs an extra punch to the gut, nothing sounds out of place i def dont crush no dynamics in my stuff ( i tend to give my stuff a lo fi feel anyway)
alot of songs out there today (lets say new rap music) is very loud compared to a few years ago, some of us notice it but if it fits then really theirs no problem.
my main goal when mastering stuff is if it sounds good on my monitors, and on my headphones, and then earphones, im all good, i still need to test out car speakers im sure it will still sound good.
you have to remember tho not everyone learns the same techniques, i didnt go to school for music, i pretty much got my steez from watching old youtube videos of producers like rza and them, and more new guys like lex etc etc so my style fits around them instead of text book instructions.
again tho i only double master if the vocals are not sounding right to me, i just like a certain sound to tingle my ears and if it doesnt then i need to do something about it.
