Cannot delete tracks after upgrading to iTunes 9

Question

I upgraded to iTunes 9 today. Added a 14 tracks from a new album. Then when I went in to the tag details to bulk edit the album name, it only edited 13 of 14 tracks. I selected only the last track to try and edit it singularly, but the tag info has been grayed out and I cannot touch it. I cannot delete this track, I cannot edit it, and if I delete the whole album, just this track stays.
I checked permissions and I have the rights to read write this track. The permissions for this one track are no different from any other. Help!

I've encountered problems similar to this. Here's how I've dealt with it.
First, carefully examine permissions issues and refresh the iTunes library info if necessary. If you don't have write permissions for the folder containing the files or for the files themselves, iTunes will refuse to rewrite the tags even though it appears to take. You can set this by going to the Finder and using Get Info. If you've already added the files to your iTunes library while they were write locked for you, you will need to clear them from your iTunes library. For this, I typically copy the source audio to another location, delete the original location, remove dead tracks from iTunes (using Doug's Super Remove Dead Tracks ( http://dougscripts.com/itunes/scripts/ss.php?sp=removedeadsuper )), then copy the files back to their original location (with all permissions issues solved) and trying adding to iTunes again.
Even trying this, I've found some strangely coded mp3 audio tracks that don't allow you to alter tags in iTunes. I've gotten around this by importing each mp3 track into Fission (third party app) and saving back out as a new file. Fission doesn't reencode the audio, so you don't get additional lossy degradation. Doing this will clear up the quirky file headers/wrapper/metadata to make it iTunes tag friendly. While this last solution is tedious, it does fix finicky files.
