Slashdot loves this topic, people with shitty speakers, crappy equipment, tone deaf, and with no musical background, likely almost never going to hear a real live orchestra in their life loves anything that puts the audiophiles back in their places.
I used to be in the following camp, I cleaned out the earwax, now I go to orchestras and hear what I'm missing, it only took a 70 dollar investment in some Grado headphones to listen to stuff and go... This sounds really bad, it sounds really weird... (You can't see bitrates on mp3 players, so when I went home I discovered why all my Beatles sounded awful, 128kbps while most everything else is 192 or higher. I could also hear stuff I ripped back in the late ninties with compression artificats ripped at 320, just from advances in technology, the software has improved so much as well
128 to 320kbps doesn't make the vocals or big pounding bass sound better, it makes all the little background sounds and notes become something other than fuzz, it makes the vibrato sharp and crisp, it allows you to distinguish every background vocalist individualy instead of one merged unison. The 'unimportant' bits return.
1/3rd can't tell audio bitrates, *Gasp, Shock* and Half the US population doesn't believe in evolution. The majority of Americans eat predominantly con-agra and kraft chemicals for breakfast lunch and dinner and haven't tasted a fresh vegetable in years and see no problem with it. So this is proof bitrates are garbage? Hell look at the Musical Tastes of the majority of people... Of course you can't hear a difference. Just because mainstream NFL halftime hip-hop and crap-soulless-corp-rock sells better than classical music doesn't make it better music or make me value their opinion.
Hell, lets do a study, 1/3rd of people likely can't tell the difference between IE6 and recent anything else, does that mean browsers are crap? Of course not.
Audiophiles win this round, just because most people have become deaf and numb to quality doesn't mean I have to. This applies to food, knowledge, media, sweeteners, music, video, furniture, computers, operating systems, etc.
