I just discovered something a little disturbing about the new iTunes. My grandson has a login account on my iMac with his own iTunes library and AppleId for purchases. Going into the new Purchased tab there were some things that he bought but were not there. I think they were purchased on an older machine and just never got put in the current library. I clicked the cloud and got a message stating basically if I tried to redownload his stuff to this iMac it would be 90 days before I could use the feature under my iTunes and AppleID. I would have thought that any account on the computer could use this feature without such repercussions. I am glad that only he and I have iTunes on this machine..I pity the family with 2 adults and 2 kids on the same machine..of course i realize this is a beta so hopefully maybe they will change that.
