This means that, using a "perceptual coding" technique, parts of the music signal are discarded.
Have you ever wondered what the discarded parts might sound like? I have, and so has composer Ryan Maguire, who is releasing compositions using what he calls "The Ghost in the MP3".
I discovered this (and was fascinated by the sounds I heard) listening to Spark, on CBC Radio on my way to work Wednesday afternoon. Here's a link to the Spark segment podcast (only 6:42, well worth the listen) and a bit more background:

Here's a link to Ryan Maguire's web-page:

He has (uncompressed) music files you can listen to (free) on bandcamp:

And here's a link to his paper which gives a deeper background on the whole subject:

Fascinating stuff. I know I'm a weird techie, but it's still fascinating stuff.
