Certain .m4a files do not play

Certain .m4a songs just don't play in iTunes 7.0.2. The files are recognized and show their true time length but iTunes just skips over them, racking up the play count along the way.

These songs have played in previous versions of iTunes and will play from the Finder and in Quicktime.

My solution so far has been opening in Quicktime, converting to WAV and bringing back into iTunes to convert to mp3. This really stinks because my songs lose their track info during the conversion and it's a pain to replace.

The only patterns I can detect is all of the problem m4as have been encoded with iTunes 4 (ranging from 4.4 to 4.9), although MOST m4as encoded with these versions do play. I have albums all encoded the same, yet randomly one or two songs are bad.

Attempting to convert the problem .m4as to mp3s or any other format from within iTunes yields an empty file.

I've tried changing the permissions on the song files but that doesn't work.
