Why is KIES only downloading song title info. on certain songs?

[AC Question]

This problem is showing up in my Google Play app. A big selection of songs from my more recent iTunes purchases are being downloaded without artist, or album artwork. I transferred the files from iTunes on my mac air to kies and then moved them to Samsung Note 3. I don't want to manually update over 100 of these songs. Is something wrong with these files? Some are recent and popular songs purchased legally so I am confused why the information doesn't carry over. Can this be fixed? Thanks for your attention and time!
