Music wont sync to iPhone 6

same here, from looking online it appears that this is a bug affecting iPhone 6, just spent four frustrating hours trying everything to no avail. I have playlists and songs in my library that simply won't synch. Makes me wonder why I spent money getting the 64 storage!! Sort it out Apple, not good enough!

I use manually manage and then drag and drop the files to the phone - got my 6+ yesterday and am in process of setting it up but this is working for me (albeit with some files not going on the first or second time I drop them to the device - I do not like how iTunes 12 is laid out).

I tried to drag and drop but although on the screen it said it had worked, when I checked the phone the songs did not appear. Really really frustrating!

rreally weird, I went back and then checked all the options in settings together and then was able to get my music on the phone - not going to chance pressing synch in case it wipes it! Surely it shouldn't be this hard to add a playlist from the library to the phone? There's something amiss either with the itunes 12 update or with compatibility with the iphone 6 or perhaps both?

I'm having similar problem, but I do transferred some songs to my iPhone 6, the problem is, many songs just don't get transferred. Check the image attached. The songs in black were transferred, the ones in grey with a little circle were not.

I checked all the settings and there is nothing I can do. I'm stuck.
