Also, from http://www.mp3-converter.com/mp3codec/imperceptible.htm :

Who Defines "Imperceptible?"
Before moving away from the topic of perceptual codecs, there's an important
point to be made about the category as a whole: They all make baseline
assumptions about the limitations of human perception, and about how closely
the end result will be listened to. The fact of the matter is that all that
stuff being stripped out adds up to something. While no recording format,
whether it be vinyl, reel-to-reel, compact disk, or wax cylinder, can capture
all of the overtones and subtle nuances of a live performance, nor can any
playback equipment on the face of the earth reproduce the quality of a live
performance.
All compression formats-especially perceptual codecs are capable
of robbing the signal of subtleties. While certain frequencies may not be
distinctly perceptible, their cumulative effect contributes to the overall
"presence" and ambience of recorded music. Once a signal has been encoded,
some of the "magic" of the original signal has been stripped away, and cannot
be retrieved no matter how hard you listen or how good your playback
equipment. As a result, MP3 files are sometimes described as sounding "hollow"
in comparison to their uncompressed cousins. Of course, the higher the quality
of the encoding, the less magic lost. You have to strike your own
compromises.
[...]
In a perfect world, we would all have unlimited storage and unlimited
bandwidth. In such a world, the MP3 format may never have come to exist-it
would have had no reason to. If necessity is the mother of invention, the
invention would never have happened. Compression techniques and the perceptual
codec represent a compromise we can live with until storage and bandwidth
limitations vanish for good.

Currently the only reason, as a tango DJ, to persist with mp3 on a laptop is
because specialized DJ programs (that are cheap and/or free) still do not
handle much else, as far as I know.
I decided in January 2003 that I prefer lossless compression to using a
specialized DJ program, so I have been DJing from a laptop with
losslessly-compressed tangos (ape = "Monkey's audio") ever since, using an
external "audiophile" soundcard (and a good amp and large speakers). Works.
