Q: Iphone 5s not syncing music to phone with itunes 12.0.1.26 - also cannot download full purchased albums, only some tracks

The fun of new updates on my Windows 8.1 laptop and iphone 5S 64gb.

I noticed since my last sync that some tracks had magically been removed - so I wanted to full sync. This couldn't even be instigated unless I deleted all my music off of phone, now it just hangs when syncing - for hours. No updates on how many tracks out of how many tracks have been synced.

Also my purchased albums - I can see them on itunes as whole ones that are purchased, same on iphone.

I then go to iphone to download my purchased items via itunes app, and it only shows some songs. An example is Drake, Game etc. - seems to affect full albums I've bought that are "deluxe" editions.

All the normal/single edition albums seem fine.

Absolutely fantastic, can't get my music onto phone except some purchased items - and even then it doesn't show all my purchases.

Not sure if setting up family share affected things, but it can't even handle the simple tasks let alone downloading content from other users purchasers (which it detects fine ironically). New features but can't do anything that has previously been fine.

Flabbergasted, had one work iphone4s 16gb and 64gb personal previously - no problems with same laptop.

My alienware laptop is very high spec with SSD, so the fault does not lie here - apple related software or product.
