I have an iPhone 4S, a Lenovo T410 with the latest iTunes installed (Win 7), and authorized as well.
I can transfer most songs.
For some reason I can't transfer some songs from my iTunes library to my iPhone.
Not all songs have been purchased from my PC, and not all songs have been purchased from my iPhone.
One of those songs I can't transfer is actually bought from my wife's Mac Book Pro - but through my account and credit card.
A while back I backed up the songs my wife bought through her Mac Book Pro to my Lenovo T410 - and since all songs have been purchased through my account I presumed that I can transfer those songs to my iPhone as well?
My wife and I have the same accounts on our iPhones as well, since we think it makes a lot of things easier and cheaper.
Is this noraml behaviour?
