Okay, now you're providing specifics.
Nothing to do with CD formatting. Audio CDs do not contain track information other than generic basic (track1, track2, etc). Your computer has a database that associates information on CDs you have inserted that is garnered from a central database (Gracenote). Are you trying to change that information, or are you trying to change information in files you may have ripped? And I take it this is an audio CD and not a mp3CD?
Okay, so you dragged the files from the CD into an empty iTunes Playlist? Now you're having problems editing some, or is it all? Have you checked that the files that are presenting problems aren't locked or have special permissions issues? In Finder get info on a file and check if it is locked and that you have write permissions (near the bottom) . You are sure they are all MP3?
I opened the original file in 'Finder' and under 'GetInfo' found that the locked box was checked. I looked near the bottom of GetInfo for write permission but all are grey (means I do not have permission).
However, by unchecking the locked box, I was able to do all types of editing of the file in the iTunes. So my problem is solved and all my MP3 songs CDs can be used now.
Thank you very much for you assistance. Much appreciated.
My version of this problem:
1. Purchased "Opening Titles" from SHERLOCK tv soundtrack on iTunes.
2. Renamed it "Sherlock Opening Titles" from within iTunes (by clicking twice, not by using Get Info). Definitely was in iTunes. Did NOT screw around with folders or names in Finder mode.
3. Added song to a playlist called "TV Faves" which I maintain alphabetically (by song name).
4. Couldn't find it under S!!!! Instead, it's under O. There it sits... "Sherlock Opening Titles"... right between "One Day at a Time" and "Outer Limits." How do I make iTunes recognize the changed song name?
