I know the underlying science for representing analog sound in a digital format but I'm missing something important. More than a few new and older* CDs are quiet. *(Stuff originally recorded back in the 70s, i.e. not new music). If I go from the radio to a CD, I have to turn the volume up to get the same (seemingly) sound level. This is in many cars, or home players. That may be bad example; but I also notice different sound levels when I take songs from different CDs and make my own collection.

So the question: is there a reason this is so? Do they figure on better sound reproduction if the amplifier is producing the volume, rather than the source? Or is it to have more head room, space for loud crashes? Something else?
