Did not work for me.
Here is what I've done:
- I've rebuilt my library
- then spent 5 days on my library to delete dupes
- re-encoded some low bitrate songs.
- deleted songs above 200Meg (DJ mixes)
- fixed any missing covers.
- then I marked all my music as "iTunes U" to get an empty music library.
- started iTunes Match. Went through the steps 1 to 3 - finished
- pulled 50 songs back from iTunes U and restarted the match.
- went through step1 to 3 in half an hour!
- moved on with another bunch of 200 songs, stucked at step 3 song 20.
- stopped match and restarted iTunes. This time it went through.
- moved on with another bunch of 200 songs, stucked at step 1.
- stopped match and restarted iTunes, stucked at step 1.
- checked some threats here how to fix step1 issues. no luck. was not able to pinpoint the song who causes the trouble.
After spending 12h in this loop I gave up. Decided to wait for any update to give iTunes match another try.
What a dissappointment...
