Apple has released iTunes 11.0.5 to fix a bug with iTunes in the Cloud.
The issue seems to be similar to the one that was fixed yesterday in iOS 7 beta 6.
Here’s a brief description of the issue:
This update corrects an issue with iTunes in the Cloud, where some purchases may download or play unexpected items.
Apple had released iTunes 11.0.4 in June to fix a problem that used to cause iTunes to quit while switching between wired and wireless syncing. It also fixed an annoying bug reported by some users, which required you to login to iTunes repeatedly.
Apple has also seeded iTunes 11.1 beta 2 to developers, which seems to also include a fix for the bug with iTunes in the Cloud. iTunes 11.1, which is expected to be released alongside iOS 7, includes new features such as iTunes Radio, Apple’s upcoming Pandora-like music service.
