I started re-ripping all my hundreds of cds to aac files in itunes and discovered that itunes makes a duplicate entry in the playlist and does not write over the mp3 version of the same track.
So the delima is: can an applescript be written to run through all tracks and move or delete the mp3 version of a track if an aac version exists?
If this is fairly easy, can you point me in the correct direction?
