Certain songs won't go to my iPhone 4

- Everyone in my family uses a different Apple ID
- I recently took lots of songs from various family members iTunes and put them in mine via Home Sharing
- I updated my iPhone 4 to the iOS 7 beta with a complete restore
- I then switched it back to iOS 6.1.3 via a complete restore
- Now, all songs from my mother's iTunes won't go to my iPhone 4
- I have tried de-authorizing and re-authorizing the account, un-checking and re-checking the songs, and everything else, but they still won't go onto my iPhone 4
- All software is up-to-date

Anyone know how to fix this???
