So I have a bunch of music that I bought on iTunes currently on my wife's laptop.  When I had my 5s I connected it to the laptop and sync'd up to have all of that music on my phone.  I got a 6s back in December or so, and when I tried to load all of that music onto my new phone I got an error saying the iTunes didn't have the most up to date version.  I verified it did, so now I've got all of this music and cannot get it on my new phone....any advice?
