I cannot sync my Iphone 6 . I keep getting a message that says "1 Item failed to sync. Please see ITunes for more info"

Question

I recently got an IPhone 6+ a few weeks ago. The 128 GB version. So far, I've loved it. I love the screen size, I love being able to put as much music and movies on it as I can. At least theoretically.
For whatever reason, I cannot sync and put music and movies on my phone. No matter what I do, what settings I change, or how many times I Google it, I keep getting a message that says
"1(Or just) Items failed to sync. Please see Itunes for more information"
Every time I try to sync my phone, I get this message. I have a library of 1300 songs and entire seasons of shows that play just fine through Itunes but for whatever reason will not sync to my phone. It doesn't matter if the songs were ripped or bought from Itunes, I cannot get more than a handful of songs onto my phone anymore.
Has anyone had this problem recently? Most Google searches only found information from 2011-12. And again, every "fix" I've found from Googling has not fixed this problem.
What's the point in a 128 GB Iphone if I can't put anything on it?
Thank you for your advice and direction.

Ok....so I have found a work around....if not a complete solution.
I'm not sure if deleting your music, uninstalling ITunes and reinstalling and adding your music back will actually affect it but I tried it again. Started from scratch.
I checked the box for "Manually manage music and videos"
Then I moved my music to phone via drag and drop, usually just boxing a row of albums at a time.
I went back into my Iphone and began the sync. The message popped up, "1 Item could not be synced" and the sync stopped. At that point, I just clicked sync again and it started back up again. It took a few go's but eventually I got all my music on my phone.
Ironically enough, the only songs that wouldn't sync were songs that I had actually purchased from Itunes....kinda odd
