Thank you so much for reading this. iTunes isn't finding approximately 1/4 of my music tracks, even though the tracks are in the iTunes folder. The easiest way to describe it is this. I open iTunes and go to an album that has ten tracks on it. But when I look at the album in iTunes, anywhere between two and four of those ten tracks are not displayed. It's as if they are not/were never there. YET, if I go into explorer (this is a PC) and look into the actual iTunes folder/files for that artist, it's right there, all ten tracks! So, the next thing I do, while still in explorer, is double click a track that iTunes couldn't find; iTunes then opens and plays the song and, yes, that track is now being displayed by iTunes. So, I know the track is there. I know iTunes can find the track, but only if I go into the iTunes folder. This wouldn't be such a big deal, but we're talking about approximately 1,500 of these "lost" songs, and it would be essentially impossible to go through and "show" iTunes where each song is. I hope this makes sense. Thank you very much for reading this. I appreciate any suggestions.
