Unchecking this box indicates that you do not have the rights to sell this track and consequently it will not be for sale in the iTunes Store. According to your contract, (subject to limited exceptions set out in the contract) you must allow iTunes to sell every track for which you have the necessary rights. If you do not have rights to sell the track, you should uncheck this box and still upload the track(s) in question in case you do obtain rights in the future. Since the track will not be for sale or visible on the iTunes Store, the album will be considered partial.
Un-checking the Cleared for Sale box does not make a track "Album Only."
