ITunes Pre-Order not working properly?

I ordered an album from Savant a week ago, and it released yesterday. However, it didn't download at all my devices(iPhone, MBP), only on the one i purchased it on (iMac)… Is this intentional or a bug?

Connect the iPhone to the Mac. That will cause iTunes to open and it will ask if you want to sync. Done.

What is an "MBP"?

To add purchased items to another Mac, add them as "authorized" computers. In iTunes, go to the top menu bar, Store > Authorize this computer.

You're assuming people have a Mac or computer to connect to. If not, then what?
