I have two iTunes accounts (my main account and the very old one I used to buy songs with before I subscribed to .Mac and switched to that ID). Now I use family sharing with those two accounts which works fine except for a few songs that I bought when DRM was still implemented. These are listed in the Purchased section but have never been upgraded to non-DRM files by Apple. (Probably because they were pulled from the store before DRM was dropped.) So I can re-download these songs with my newer main account via family sharing but they won't play. My Mac is authorised to play content from both accounts but it's no use. Anyone else with that problem?
