Apple to Delete All iTunes Match Libraries Tomorrow to Prepare for Launch

Apple has informed developers that it will delete all iTunes Match Libraries tomorrow.

As we prepare for the launch of iTunes Match, we will be deleting all current iCloud libraries on Saturday, November 12th at 10 AM PST.

Please turn off iTunes Match on all of your computers and iOS devices. On your computer, choose Store > Turn off iTunes Match. On your iOS device, tap Settings > Music, then turn off iTunes Match. On your Apple TV, please choose Music > Turn off iTunes Match.

The songs on your computer should not be affected. As always, please backup regularly and do not delete the music you add to iCloud from your computer.

Apple had originally announced that it would offer iTunes Match by the end of October but was not ready to launch at that time. It's unclear if this will be the last reset before launch.
