I find the third option the most likely: iTunes rewrites the data file
frequently. Is there a way to lock the file while reading it, or
detect if it is being modified, or suchlike? Thanks.
You aren't guaranteed that the iTunes library file will always be a
plist. The "correct" recommendation, which will also solve your issue,
is to use Apple Events to get the information you need.
In the general case, since you didn't write -[NSDictionary
initWithContentsOfFile:], you can't make it safe. You'll have to open
the file and read it's data yourself, then hand that off to the
NSDictionary initializer (or perhaps NSPropertyListSerialization).
