itunes strange behavior

[juan123]

I recently ripped some CDs on a PC as mp3 files.....when I open them with itunes on my mac they don't copy to my library like other Mp3s that I have on my ibook. I also tried dragging these to my library but they don't copy either. These files do play with quicktime. I have OS X 10.4.10, ibook G4, itunes (the latest) 7.3? Well thanks for any help!!
