I just followed the directions above for restoring my itunes library.... basically most of my music disappeared after i created a second library on the same computer. After doing so, I could no longer access my first library at all (pressing Option when re-opening iTunes should have let me choose my other library). Instead, only a few random songs appeared. So, I've just restored my library, and now what do i do about the itunes file on my desktop and the one in the Trash? and also, i have several "previous itunes libraries" files now and don't know which is what, etc!
