iTunes Match - AAC - Uploading
I have a real annoying issue that seems to happen a lot. I doubt there is a work around, but I will ask anyway. I have a lot of CDs that I ripped years ago that are 192kb. After I import them into iTunes I add them to the cloud and they match. I then delete them locally and download them from iTunes. After they are all downloaded I select them all and select create AAC version. I then delete from the cloud and local computer the original versions I download. I then try and match the converted versions and only about 70-80% match. I can't figure out why they don't match if the only thing I did was create an AAC version from their downloaded version. Needless to say this is very annoying and driving me crazy. Any help would be greatly appreciated. Thanks!!
