Not to mention that a smart enough lossey codec can be used to generate
better then cd quality:

For example, 16bits of cd audio, might be enough for signal to noise ratio,
but it's really not enough dynamic range. High bitrate vorbis, with sutible
A/D, and D/As has the potential to sound better then a CD at a comparable
or lower bitrate (i.e. by not wasting bits on stuff that you can't hear).
