Hidden purchases and logging off
Hey, I have two apple accounts. In the first one I have all of my bought purchases and in the second one I haven't bought anything.
I have half of my music downloaded all the time, and whenever I log off my first account the other half dissapears and I have to download it again from a menu called "Hidden purchases". How can I unhide these songs or make them not dissapear whenever I log off the first account? I use the second account a lot and I can't be downloading music every 3 days.
