[iTunes] Redundant Audio Tracks

[John]

Sorry I'm jumping in late here . . . not too sure if this was mentioned 
before.

Check your preferences - is iTunes set to import music when adding 
music? This will create a new copy of each music file, and that will be 
put in the Music/iTunes/iTunes Music folder. The original files will 
not be referenced by iTunes.

The other thing to do, is to go in iTunes, get info on a track, and 
look under the Summary tab. At the bottom is the path of the file 
iTunes references.

You mention two different song counts - see which files are unique to 
the one location, and see where iTunes references them.

Hope I'm not stating the obvious . . . if so, don't take offense!
