I have all my music on my user account on my MacBook. My wife also has an account on the MacBook with a small amount of music. I want to share my iTunes Library and then add her smaller music collection to it. I figured this is the easiest way for us to pool our music but still have a separate account for emails, calendars and contacts that we can sync with our iPhones. I moved my iTunes Media folder to the /Users/Shared directory and pointed iTunes to it; no problem there. I logged into my wife's account, renamed her iTunes Music folder (so I can copy all the MP3s, AACs, etc over to the shared library later) and opened her iTunes. I tried to point her iTunes to the shared iTunes Media folder but nothing happened; no prompt to copy files, no adding of existing files. I opened iTunes while holding alt and tried to choose the shared iTunes Media folder but it tells me that it cannot find an iTunes Library. There is an Apple Support document that gives instructions on how to share iTunes libraries but I don't like the idea of constantly having to go to File > Add To Library every time either of us makes a change to the 'shared' library. Is there a way for us to both have (asynchronous) access to a shared iTunes library without having to manually scan for updates? Or, is there a Lion/iOS5 feature that I've missed or misunderstood that can simplify this for us?
