Can't import songs with titles containing the word "Down" into iTunes
I have 9 songs in iTunes that have the word "Down" in the title, and every time I try calling any of them up, I get a message saying "Cannot locate this song." The titles and album info. and durations are all listed in the library, but the actual songs don't seem to be there. (And when I synch the library to my iPhone or copy the songs to a thumbdrive for my car: same thing. The songs with "Down" appear in the list but don't actually seem to be there.) Any clue what's happening? This never happens to any of the other thousands of songs in my library.
