iTunes wont add some songs

[CorporateFelon]

Trying to add an album of mp3s, but for some reason only 2 of the 17 songs will get imported. I've tried adding the whole folder(which I normally do). Adding song individually, even dragging the files into the iTunes window. I can preview all the songs when I right click -> Get Info. I just can't add most of them to iTunes. QuickTime will even play all of them.

Any ideas? Corrupt mp3s?
