Why is the "Time" for a track listed as "Not available" in iTunes?
I ripped a number of CDs into iTunes. I noticed that several of the tracks do not play, and they list "Not available" in the Time column of the track list. The file exists on disk, but it will not play in QuickTime either. I assume that some sort of file corruption has happened, but why are there so many? Is there a known issue that causes this, and is it preventable? How do I fix it without deleting the whole album and re-ripping it? This has happened on a number of albums.
