Thank you for reading this. I regularly find music tracks which will not play out of the iTunes library (I get that darn spinning beach ball), nor will the synch on to the iPod (they cause the synching process to hang up and I get an error message). I am assuming they are corrupted, if that is in fact the proper word. Is there something built into iTunes, an applescript, anything at all out there which can go through my library (I have about 12,000 songs) and locate all of these corrupt files so I can re-rip them? Or perhaps is there something which can fix them? Thank you.
