I just got a mac. Itunes for windows had the same problem.

I add my mp3 collection, 99% of it i ripped myself from my own cd's and it wont take some of the mp3's. It will take other songs from an album but leave out some. I try a song that it leaves out with dj-1800 and it wont play them as well.

But I take the songs that itunes wont play and play them in audion and they play fine. I know there is nothing wrong with the mp3's.

any idea's?
