Hahaha well just pointing out ... that there's listening sound loss with all people dependent on age. However for those that don't have any sound listening training then they might not won't differentiate between a 320 kbps or 128 kbps or 650 lossless playback!

And b/c they hear one song at 128 kbps that sounds reasonable they then take that as the norm & say it's ok to convert all songs at this sound quality. ... eeeek!
