You guys keep talking about audio quality like 99% of people even realize that itunes quality is not "good". Apple is smart keeping the audio quality down(keep filesize down). Honestly i couldn't care less between 128kbps and 256kbps. Sounds fine to me.
However, anything lower than 128kbps has a very noticeable change in sound quality. I can tell the difference between 96 and 128, but 128+ is all the same to me.
I guess my ears suck.
