When I copy music to another library, why is the "Date Added" field is not transferred over along with all the other track metadata?
Unfortunately, iTunes does not allow modification of the Date Added field, either by another program or by manually typing in a new value. As a result, whenever you perform an operation that imports new tracks into an iTunes library, those tracks will always have the current date set for their Date Added value.
iTunes is displaying a message saying "The iTunes Library file cannot be saved. An unknown error occurred (-54)." What does that mean?
The most common cause of this is when you have an iTunes library that is open by two copies of iTunes at the same time. This can happen if you share a library between multiple user accounts, or use the same library from two or more computers across a network. If this is the case, you will need to quit all but one copy of iTunes that has that library open.
I was performing a long copy/merge operation that was halted, saying a timeout occurred trying to quit iTunes.
The most common cause of this is when iTunes has opened up an alert or other window that has not been dismissed. This includes the iTunes preferences window, the info window showing details of a track, or an alert asking a question that requires a response. If one of these windows is up, then iTunes will not quit or respond to any other commands sent to it by PowerTunes until you dismiss the window in question. Some common settings you can change to prevent this from happening are:
- Change your podcast downloading to manual. iTunes will sometimes automatically start downloading new podcasts in the middle of a copy operation. If podcasts are still downloading when iTunes is asked to quit, it will put up an alert asking the user whether they want to finish downloading before quitting. This will prevent iTunes from quitting.
- Similarly, automatic downloading of album artwork with put up an alert if artwork is being downloaded when iTunes is asked to quit. Automatic artwork downloading can be turned off in iTunes preferences, but iTunes will still update its artwork cache for new imports, which leads to a similar problem, and this behavior cannot be turned off.
How does having multiple libraries affect purchases I've made at the iTunes Store? Do I have to authorize separately for each library?
iTunes Store authorization is kept in an entirely seperate place from the iTunes library and music folder, so once you authorize your machine for your iTunes account, this authorization will apply to all your libraries. You may need to log back into the iTunes Store itself when switching libraries, to change settings or make a purchase, but you can continue to play authorized music without having to type in your password all the time.
