I have a very few CD's that are pop CD's that I actually enjoy listening in a critical manner. While at Mark's Sound Quality Seminar before Tulsa, he showed us this quick video on what the record companies are doing to CD's. After a bit of research, I found the video....

my biggest beef with the record industry is a lack of standards, the sound engineer has total control on the quality. some care and produce good albums, some don't and produce crap. it's unfortunate, there are some great bands that have crappy recordings. example, old Foo Fighters sounded good, new Foo Fighters sounds awful.

there's a site i've seen where they rate the top 100 best and worst produced cd's. it was surprising what albums were produced well and which ones weren't.

I have bought several new CD's lately only to be severely disappointed in the quality of the recording. Most appear to suffer from the loudness adjustment. It's just a shame that some really talented musicians end up with their music ruined by some idiot sitting behind a mixing console. Where have all the really good sound engineers and recording studios gone????
Just to add some fuel to this discussion. You should "see" what compressing music does to the quality. I took a good live recording and analyzed it using nero. I then took the same track and ripped it at the highest bit rate MP3. I even tried some of the formats that claim to be lossless. I haven't tried FLAC yet, but I will. Take a look at the difference between the original recording, and the "high quality" MP3 recording.
 I analyzed the exact same point in the track. Sorry for the small image. The top window is the original, and the bottom is the MP3. Take special note of the frequency response curve ( the two black boxes at the bottom of each window). You will see that all the data in the upper range is gone. I plan to do this test in the car using the RTA to see what the difference is in the car.
So does anyone still think it sounds the same? If most people think it's just as good, does this mean the majority of the population has complete hearing loss above 10KHZ. I admit I have listened to recordings in MP3 that I thought sounded good..... until I heard the original uncompressed recording.

I'm very disappointed to see this, but not surprised. I listen to Van Halen "Van Halen" and can turn my volume to 78, then go to a rammstein track that is recorded for LOUD and can only turn it to 66 before the whole system distorts. Very sad, indeed.

That's on my "To Do" list. I've ordered an original recording for just that purpose. I should have it in my hands by Thursday and I'll post the results.

CLS- very nicely displayed! Just to CLARIFY- however, what you are showing are the evils of data compression. The OP's article is referring to dynamic range compression. The two are different, separate issues. Both have a deleterious effect on the music; both combined are enough to make one cry. Not picking on you at all, I think your post shows what a lot of people may otherwise have a harder time grasping or believing. Just wanted to point out that it is not the same thing.

^^^Yep. Sorry I got a little off topic there. I get a bit fired up over what's being done to music these days. I did realize they are different problems, but just imagine what happens when you take the original CD that was recorded so poorly for loudness, and compress it to MP3. You then have a recording that has NO dynamics at all, and basically is just a bunch of noise. . I compared the FLAC to a original. I'll post the results in another thread so I don't pull this one off topic any more than I already have.

I've done similar tests in Nero wave editor, with similar results.

This one is on topic. I have the new Robert Plant/Alison Krauss CD "Raising Sand". I like some of the songs but think it sounds distorted in my car even at low volume. I wonder why??? Well, this is likely the cause.

They expanded the overall level so much, it's actually clipped in some areas. What a bunch of Morons!!!
One more example: I bought the One Republic CD. I liked the songs but again, the quality is horrible. Here's a shot of Apologize from the CD.

Once again, they expanded the level so much, it's clipped.
Is there anything produced now that isn't pure crap????

Rush - Roll the Bones Pink Floyd - anything Eagles - Desperado, HotelCalifornia Bella Fleck and the Flecktones - Ride of the Cosmic Hippo Van Halen - anything pre-Hagar Queen - all but their compilation disks the list goes on, unfortunately MOST of the new releases, adn remasters are compressed for loudness.

^^ I've got a lot of those. It's just a shame I can't buy anything new. I would like to add some new stuff to my collection, but I have to be able to listen to it. I even had to take a remastered copy back the other day. It was originally released in 1990 then re-released in 2007. Guess what the re-released version sounded like. 
Fortunately, OZ music can still order original out of print CD's.
