Music will not download onto iPhone?

My iphone won't sync new music to it. When i plug it in, it syncs the old music, but not any of the new cds i put on. I tried deleting all the music off my iphone and resyncing everything but it still isn't working. I also tried restarting my iphone, and i checked for updates for itunes and my iphone, but both are up to date. The music just will not sync!

I didn't like Christmas this year?

I don't have my cell phone. I just didn't have a good Christmas this year. My parents kept asking(well yelling) why I was so in grateful for my presents even though u I said thank you and I'm ver grateful. Is this a lot for Christmas.cuz most ppl on youtube said they got iPhones and laptops and this feels like nothing to me even though I originally got a lot. I just really wanted my phone I think which is not an iPhone. I'm 14.

My devices are deleting everything?

Okay. I got my iPhone 5 in december 2012, I got an instagram, and a kik, a twitter and all other social networking. All worked fine until my instagram pictures deleted themselves, that turned into deleting tweets, comments, followers, making me unfollow people, on EVERY social network! Even deleting notes in the NOTE app. It would kick me out of snapchat and kik messenger and id log back in and people would be blocked. Finally I.dropped that phone and was forced to get a new one, I went through about 3 more refurbished iPhones all experiencing the same problem so I got a refurbished galaxy s3. The same problem! Every time I.got a new phone, I changed everything I even set them up with a brand.new email. The only thing the phones had In common was my phone number. When i'm on twitter on my laptop things delete there too, by the way. Today for christmas I.got an ipad mini, it does not have a cellphone number but I set it up with a apple id. New social networking, every thing. Same problem
