My wife and I both have large music collections. We share my iTunes Store account, but she has her own iCloud account.
We recently had cause to add her music to iTunes Match. To keep our music separate, I was just going to make a regular playlist with each of our names and add to each the songs we were respectively interested in.
My idea was that for our Smart Playlists (My Top Rated, etc) we could simply add a criterion that the song must appear in our personal playlists. But lo and behold, iTunes told me that
Smart playlists that reference other playlists are not supported by iCloud, and will not be uploaded.
Well, that's just great.
We could buy a second iTunes Match account for my wife, but then she would have to start using her personal account for all Store purchases, meaning we'd have to buy all her apps, books, and other non-music iTunes things all over again.
So it looks like I'm screwed, and that the only resolution is going to be that we have to start syncing via iTunes again instead of iCloud. But if there's any workaround that lets me listen to my favorite songs without hearing all my wife's favorite songs, I would love to hear it.
