Dennis Rogers has pointed out that Rolling Stone magazine has an article called The Death of High Fidelity, about one of the negative effects that the influence of MP3 audio has had on the audio quality of recorded music. I featured something about this last summer at this link.
Not to get too nerdy-techie, but there are two forms of compression involved here. There’s the compression of the audio signal, that makes everything have the same loudness, and there’s the digital compression that is used by MP3 and other audio formats to reduce file size. They are two very different things.
Matt Mayfield, who I’m assuming is the guitarist in the recently-disbanded band Moses Mayfield, has a video that I’ve grabbed from YouTube, with an excellent explanation of what audio compression and loudness are all about.
