Music not syncing to iPhone 6
I could download my purchased (through iTunes) music, but those are now the only songs on my iPhone 6.
Obviously I have iOS 8 on the phone, and I have 10.9.4 on my MacBook Pro, with iTunes 11.4. With the iPhone connected and the appropriate playlists and albums selected under the Music tab, I press sync and apps sync, photos sync, but music doesn't -- at least not completely.
When I select the "On This iPhone" tab and Tones, all 9 of the ring tones I've created are there. With "On This iPhone" and Music selected in the left side menu bar, I am told there are 1767 items, but every item (other than songs purchased through iTunes) is grayed out.
This makes it look like the music is trying to get to the iPhone, or is partially there, but it clearly is not there.
Thanks for any direction/thoughts/ideas on how to correct this.
