Some compression algorithms (i.e. mp3) remove what they consider is
"unimportant". However, the result after decompressing is a poor
recreation of the original signal.

That is a value judgement which most would disagree with not to mention
that your example is not valid. MP3 does not *remove* anything from the
signal. It is a form of compression that simply can't reproduce the
signal exactly. The use of the term "poor" is your value judgement.
Most people would say an MP3 audio sounds very much like the original.


Here's a reference - Neil Young and Steve Jobs, no less.
