Appreciate the info and suggestions.
I only would like to preserve Track Name, Artist, Album, and Album Artwork. Rating would be ideal but not a priority.
Copying an MP3 in Windows explorer then opening it in iTunes did not clear the Release Date for me. The SortDateAdded script works for some but not others. I haven't been able to determine what is stopping it from working when that occurs - it'll work for one MP3 but not another. If it does work, it'll work for the entire batch (album) of songs.
The other odd thing is that the Bit Rate field is getting updated too. Let's say I've got an album and every song shows 320 kbps bit rate. Once I run SortDateAdded to clear the Release Date, all the sudden some of the tracks are 192 kbps. I opened the Properties on the file in Windows Explorer and it does indeed show 192 kbps. Now did it say that or 320 kbps before I ran the script? That I don't know. I checked another album prior to running the script, each song said 320 kbps in Windows Explorer, but the Bit Rates did not change after I ran the script. But prior to testing it happened more than once so I'm positive I'm not going crazy.
Really appreciate your time and the suggestion!
