Thanks for clearing all that up Mulder and Mariush.
Does this Replay tag try to "preserve" the original sound by adding voulme and EQ info to playback because the encode has some loss or is it essentially a "loudness" button which I would presume the playback software would only need?

BTW my original loudness difference in pre encode and encoded songs was because "level playback volume" was checked in media monkey's settings. Oherwise files sound same from 320CBR to 265 VBR (plus the generation loss). That filesize went from 9.5m to 7.88 (about 1/5th). I think that's a good compromise for me.
Now I hope my car's music box accepts VBR files!....

oh one more thing... any thoughts when Lamexp will import cds. Blink 182 cd just had data files, etc. on it. And I just noticed cda doesn't work and you recommend exact audio copy. Is Itunes inferior at this. It seems so because if I remember, I couldn't get the proper import setting I wanted last try.
