MUSIC ON LIBRARY BUT NOT ON IPHONE
Alright, so I recently just got my new iPhone because my other one broke and I got the refurbished one in the mail and from my old phone I backed it up right before I did the back up onto the new one everything went smooth at all the data is there except the music it is all screwed up. All the music is on my iTunes library on my computer but every time I try to sync the phone it doesn't sync the music. I've tried everything turning the iCloud music on and off and all that such nothing is working. When you highlight the phone under the summary it says it has no music on it and on the phone actually it has some songs off my library on there and then there are songs their grade out and you can't even play them on there that I have to re-put in the CDs and get them on there that is something I still have to do but I want to get all the music I've purchased on iTunes on my phone.
iPhone 6, iOS 8.4, help
