My iTunes were & still are on my external hard drive, but I can't play them now . . . the problem is or rather began, when my son wanted to play a cd on my laptop, but wasn't connected to the external hard drive, so the iTunes asked him some questions, (he can't remember what they were!!), then itunes let him play his cd . . . now none of the tunes (all 11600 +) on my external hard drive show up & only half a dozen songs that he's downloaded do. . . now although I can go into my hard drive & drag n drop each one individually, . . . there must be an easier & simpler way to put things right? Can somebody help a screwed up old man?
