for example, if i ripped a CD a long time ago at 128kbps and i'm not happy with the quality, can i rip the CD again at 192 or higher and keep the play count, last played, date added, etc. that was on the 128?

You're not going to get 192 from 128 kbs. It isn't MP3 alchemy. :rolleyes:

You're going to need to rip from the original source again.

are you saying there isn't really a difference between 128 and 192? because i can hear a huge difference.

edit: i meant 128 mp3 to 192 AAC. sorry if you misunderstood.

If you re-rip a song in iTunes for most cases it'll inherit and replace its predecessor. I don't know if this applies when the replacement is of a different format.

depends.

if you delete the 128 kbps mp3 tracks then re rip the CD at 192 kbps AAC youre going to get completely new tracks with new play counts and new dates for last played, date added etc.

you can however edit the iTunes Music Library.xml file found in ~/Music/iTunes with a simple text editor like nano in Terminal or just use Text Edit.

just search for the title of the track, edit the details in the string, then save it and reopen iTunes. heres an example and ive bolded the parts you would edit. make sure you save a backup of the xml the file first as if you screw it up youll probably mess up your iTunes library.

I tried editing my Play Count on some of my replacement songs with no luck.
