I found this a pretty good read for those that are interested and it's been my experience as well.
http://www.uaudio.com/blog/sos-feature-loudness-war/ Other than a few bands out there that are totally crushing everything, there's a difference between loud and loud and crushed. I mix out at -3dB with a little bus glue using the UAD Fatso. When I master, I end up at -0.1 averaging between -11 dB RMS and -15 dB RMS. Max RMS may hit -7 dB...sometimes lower. Now, in today's times for some of the older folks or even older engineers, the impact makes them think "it's loud so it's squashed" when in reality, none of my mixes are ever squashed to where you hear pumping and breathing, a lack of snare drum crack nor will you ever see this:

But right away because it may be loud, I can get a bad rap for it and have before. I remember someone comparing my stuff to Metallica to which it offended me and I had to provide proof that this just was not so. In my opinion there are quite a few people that are passing judgement on music that may be loud, as being non-dynamic because it doesn't sound like an old vinyl album to them. Just because something is loud doesn't mean it was ruined. If I'm doing a rock piece that hits hard, if it's supposed to hit hard, it doesn't need to be super dynamic. I'm not saying crush it...but there's IS a difference between loud and loud and crushed.
If I did a ballad, for sure I'm not going to take the same approach. But even with an average of -11 dB RMS to -15 dB RMS that may max at -7 dB RMS in a few spots, I'm not breaking any rules nor am I degrading the quality of my audio. When you start to see -4 dB RMS max and -7 dB RMS averages....then you worry.
To be honest, and I'm a guy stuck in the 70's and 80's....I really like the new technology as well as how things can sound at a louder volume for certain styles of music. For example, I wouldn't want to hear an orchestra or even Trans Siberian Orchestra super limited and squashed. But it doesn't bother me if Maroon 5 decides to make something hot. The new Van Halen album is pretty hot...but where they failed in my opinion was, they tried to make it analog sounding and hot...so it's loaded with mid-range congestion and other mud-esq artifacts that I wish weren't there. Having a warm sound is ok...but when you treat that warm sound with techniques of today, you have to back things down or that mud turns into distortion.
I'd not want to hear Pink Foyd crushed....but I don't mind if Disturbed does it. I'd not want to hear Alan Holdsworth, Gambale or some jazz trio all limited out. See, I think it depends on the music. Certain styles are ok being loud in my opinion because it actually adds to the impact as well as the aggression of the band. Metallica over-did it and ruined that St. Anger album in my opinion. The Guitar Hero cuts of that record are 100% better. But guess what? Like it or hate it, they made history as having the most horrible yet loudest album ever made. In this industry when people are talking about you, that's great advertisement. Whent they STOP, that's when you worry. :)
The other side of the coin is, I like the sound of music today better than I did years ago. I don't like the performances as much as years ago when you had to have talent as a player/singer to make it, but the instrument sounds themselves today are sounds I welcome. The new modern guitar tones are so sick, I appreciate them based on sickness levels. Bass guitar has really improved although I'll never be a fan of distortion on a bass. It has its place, but again....it can add impact even if you're not down with it.
Drum sounds today totally rock in my opinion. I'm so tired of snares and toms from the 60's to the 80's that sounded like punching card-board boxes. Let them ring...let's hear snare strainers and a little resonance instead of felt mufflers and tape/moon-gel all over the place. There are loads of sounds we either have to accept as a change in the times...or we don't and stay true to our roots. There is no right or wrong way...but acceptance is key in my opinion.
Mixes today: definitely louder than they need to be with 2-bus glue being used as 2-bus cement that is more for squashing than using it as a weapon for tonal characteristics. I rejected 6 mixes last week because of this. If someone is going to epoxy a mix and then send it to me to master it...they might as well finish the job themselves as they leave me no room to do anything other than try to further polish their turd.
Mastering as an art: You'll never see this side of it until you master something that was mixed correctly. The key to the art of mastering is when a mix is presented that allows the mastering engineer to mold, craft, design it. By the time an ME gets a mix these days, it's already more than pre-mastered. It's a shame they don't have many albums available for you to hear before they were mastered. You'd be quite surprised at just how much the ME did to make that record sound the way it does.
When a real engineer contracted by a label does a mix, he's mixing for common ground. He's not accentuating all those lows and all the stuff we that are one man operations do. He leaves the ME plenty of room to eq and raise the levels in increments. There is an art to that...it's called scuplting and it goes beyond "a little polish". You have to live it on this end of the fence to know what it's all about. But rest assured, you can't go by the songs you hear by common folks or those posting on forums. They are mastering before they even master because they are comparing to reference material that's already been mastered. Trust me when I tell you, unless the producer is going for something specific in at the mix stage, the ME is doing a lot more work than you think because he SHOULD receive a balanced mix that allows him to sculpt it into something amazing that is an art all in its own.
