I've had to revamp my Itunes library recently after it switched libraries on me somehow, and I couldn't retrieve the old one (which was a bummer because it had a couple years worth of listening preference and history in it). The weird thing is, the one I retrieved goes back to 2006, so I found some missing treasures! Weird.
But that's not my question.
It seems in the process all of the songs became "unchecked" and will not show up in shuffles, playlists etc...I have over 40,000 songs on my ITunes, so I can't really go through and check them all individually, but I can't figure out how to select and check them all. Any hints would be appreciated.
