I have been trying to copy iTunes files from one user to another. I have come across these issues:
1) I have to log in as administrator and do a <font face = "courier"> sudo chown </font> and <font face = "courier"> sudo chgrp </font> to change ownership to the target user.
2) I don't know, where the play lists are stored. They don't seem to be in the <font face = "courier">iTunes Library</font> file.
3) I don't know, where the collection of songs that iTunes came with, is located.
