Does anyone know when songs that are deleted from one's iTunes Match account are actually deleted from Apple's servers? A few times, I've deleted a song from iTunes Match and then added it again a few hours or days later, and I've gotten a "Duplicate" error or a "Removed" error when iTunes Match scans the song. This seems to imply that songs deleted from iTunes Match aren't really deleted immediately. Does anyone know how iTunes Match handles this? Is there a set time after which songs that were deleted are actually deleted from one's account? Thanks.
