I am not surprised to hear it is taking a long time. I signed up when Match first became available. It took several days before it finally finished. I had maybe half as many tracks as you. Also, prepare for this ahead of time: Even after it finishes there will still be some tracks that do not match. This still happens even though iTunes Match has been around for a year.
To permanently delete a track from iTunes Match, check the box in the delete confirmation that says "Also delete this item from iCloud".
Supllementary Question Please!
One MBA when matching has been in a 'uploading 0 of 2' mode for two days and has returned two error messages afte two overnight sessions
One was error 4010 I believe and one was 4002
The music match has some album icons but much of the music is not there and when you hit Play it immediately jumps back to Stopped
Thanks a lot
Itunes match is for music & music videos only.
Actually, iTunes Match is for music and purchased music videos only! All your other 'Music Videos' will get deleted from your iOS device(s) as soon as you sync after subscribing.... Boo!
The only way to make available 'non-iTunes purchased' videos is to classify them as 'Movie' or 'TV Show'.
