It's interesting, isn't it?
I agree with the Elf that 'crushage' is an artistic choice, albeit with the likelihood of getting turned down significantly when played over any of the main streamers....
However, what that article demonstrates very well is that there is still considerable technical ignorance in peak level management even in the highest echelons of professional mastering.

Not a single track in that Grammy list is compliant with the EBU BS1770-4 spec in respect of true peak levels... Who cares about standards, you may ask?
Well, what that means in practice is that
half of those tracks will definitely clip the listener's D-A converter, with the rest very highly likely to clip.
There is simply no excuse or justification for that. None whatsoever. It's pure ignorance, incompetence, or idiocy.
Maybe they don't think clipping matters, or that its a nice effect... but the fact is that the audible results differ with every converter. So what the golden-eared mastering engineer hears is not necessarily what the punter hears...
And all for the sake of turning it down by a decibel or two.
