iPhone 5 won't sync all my music

[butterwm]

We just got our new iPhone 5's. Did the initial backup and sync to set them up and when it loaded the music it only loaded about half the songs. It did the same thing on my wife's new phone (different iTunes account & different computer). I confirmed on our old phones (iPhone 4) and all the songs are on there with the sync.

Any hints or suggestions on what I am doing wrong or what's different between the iPhone 4 and 5 that this wouldn't be working?

Probably a stupid question but do the phones have the same storage as your old ones? (i.e. are they both 16GB, 32GB, 64GB, what have you).

I was just about to ask the same thing.
