Just to be an old ninny...
The health limit is 70 dB. As in, pumping it to 100% volume blasting right into your ears at really high SPL's is simply abuse when you think of your hearing, not the mind-numbing shockwaves. As in, even if you have open-air headphones (which are the good ones), if people two feet away from you can discern the lyrics, you're probably hurting your ears pretty darn good.
But then, what's the point of loud "music" like heavy metal this or that (not making fun of *all* heavy metal), if you can't feel it blurring your vision? Easy answer : if you can't enjoy it at normal volumes, you are only listening to it for the Sound Pressure Level. In other words, it really doesn't matter what it is, so long as it is loud to a beat and your friends or culture idols (to whom you leave your music taste decisions) rave about it. Harsh? Sure, but let me make it clear that this only reflects the view that true music is not about the sound pressure level but about the art.
So for all the classical music lovers and any other music lovers that love music for music and not THUMP THUMP JAKKA JAKKA XING XING, this move means having a greater range of comfortable volumes. Whereas before, I could only select between levels of 0~50% of the maximum volume, say, I could select more sublevels from 0~50%. (0,10,20,30,40,50 might become 0,5,10,15,20,25,30,35,40,45,50). On that level, this is pretty good, because it make the impossible but should be possible possible.
For most people that prefer higher volumes, perhaps a minimum volume cap would have been far more helpful.
Just my 2c.
