My Itunes is not working properly either

I spent much of the day with apple support trying resolve the "greyed out" songs. I was told there was new files of the original ones I have and all the music that is "greed out" ment a several step process to reacquire them. Very poor answer, in my case it means doing this to 100 + songs. Many of them were copied from existing CD's years ago. Something isn't right here.
