For months now, I've been fighting with the iTunes software on my home computer (running Windows 7). At some point during the holidays, the library decided to stop working and point to a different place on the hard drive (I have a feeling it had something to do with a family member who caused a blue screen of death that took a few hours to come back from). Since that time, we've had no access to our CD collection and downloads from programs other than iTunes.
Unfortunately, we have more than 40,000 songs stored on external hard drives and in download folders, so a simple switch in iTunes can take days. Even after uninstalling the software and re-installing it, the program just won't open. Many hours have been spent on the web trying to find different solutions to this problem.
But then the lesson kicks in... At some point, it doesn't make sense to keep trying to fix this problem. We have other computers. I have a family to spend time with. I have work that I should be doing. And so with that, we're abandoning iTunes on the home computer and moving on with our lives. It just didn't make sense to keep pouring time into this endeavor.
