So when I download a song in iTunes and it shows up instantly on my nexus 4, is that just pretend?
Yep your nexus 4 is just an iPhone in disguise! I try to tell people about google music when the being up iTunes and the cloud and the all just deny deny deny.

I believe that is just because you have used it for a long time, if you used android I bet it would be the same thing after a while, Android is unstable, boring, stale and cheap looking. If you get a new phone I would get a Blackberry Z10. It's strong, stable, nice looking and it's high quality. Windows phone is not that bad, but it doesn't have enough apps, plus I don't buy anything microsoft.
Have you even used a Z10 I love how you can make that assumption of BB. The z10 in my eyes is a very cheap looking, your retina has been looking at the retina screen too long :x
