This morning I activated iTunes Match. There were over 20,000 songs to scan and upload, so I walked away and came back to it this afternoon. Upon returning, I found that iTunes had crashed. Now any time I try to open iTunes, the window displays but within a second (seemingly as soon as it tries to access iTunes Match, but I have no way of confirming that) it crashes. So I effectively can't get iTunes to run.

Has this happened for anybody else? Does anybody have any suggestions for fixing or even diagnosing this?

  • Which OS? Have you tried to repair or reinstall iTunes? Mar 17 '12 at 20:45
  • @techie007: OSX 10.7.3, latest iTunes. I can try a re-install of iTunes to see if that helps. Is there a specific way to "repair"?

  • I wonder if it's a specific song that's crashing it somehow (since it's scanning/uploading). If there's a way to identify it, I can remove it and see if that has an effect.

  • Re-installing didn't have any effect.

Turns out there was one or two files which were corrupted somehow. It had never been a problem before, and they've always played fine. But for some reason they messed up iTunes Match.

The way I diagnosed it was to revert to a backed up library and export a playlist of everything to a file. Then I created a new empty library and imported the playlist. As it scanned, it always crashed around the same time. I'd go back to a blank new library, manually remove an estimated number of lines from the exported file, and import again. It took a couple of iterations, but I narrowed it down to a single album.

Once I got rid of the album entirely, everything worked like a charm.
