I see this problem posted over and over. I am running osx 1.5 with itunes 2. All I did was start limewire go to preferences and uncheck the use limewire player option. Now the dl song is placed in the shared folder in LW. Once I double click it itunes opens it and it stays in my library and any playlist I choose to install it in. I have burned playlists to cd, downloaded all songs to my ipod with no problems.
