Unable to Transfer Purchases from Device iTunes 12

I tried to follow the instructions of this article(Redownload or transfer your iTunes Store purchases from an iPhone, iPad or iPod to a computer - Apple Support)

but I can't transfer my purchases from my iPod Touch (5th Gen, iOS 9.0.2) to iTunes. I tried:

• factory resetting my iPod and restoring from iCloud backup
• I uninstalled and reinstalled iTunes
• tried 2 different (authentic) lightning cables
• deauthorized and reauthorized my computer through iTunes
• and am considering trying Black Magic because I'm at the end of my wits.

I am able to sync apps and music from my device as well as make an iTunes backup.

Anybody have any suggestions?
