That's my point though. You said that 320 was OK. I think they're significantly worse still.
They're so close to cd that in a blind test of wav vs mp3 320kb LAME, true-stereo, no-VBR, most people (including me) can only guess which is which.
Where did you get the 320kb mp3s btw?
People were constantly recoding shit quality mp3s to 320kb so that they could get around restrictions on the likes of Oink etc.
