Nope. It's either mastering for a portable version (for tiny little media players) or it's simply poor, low budget work. Nothing more, nothing less.
Here in 2015, I don't purchase CD's anymore either. If I'm spending money, I want a professional 24 bit recording - and 5.1 surround would be nice too.
I have nothing against the portable formats either! Convenience and accessibility is a good thing! The more people listening to something, the better. Not everyone buys music, and that's just fine. mp3 (and pretty much the 16 bit CD format now) is simply the modern version of AM radio through a dashboard speaker. A fine thing! But it shouldn't be confused with modern professional release formats and actual modern mastering techniques.
Albums that aren't released in anything but portable quality... it's either cheapness or a bait & switch thing trying to get me to purchase the thing twice.
Cheapness is OK too actually! Bait & switch is not.
