My iphone 5 won't sync music on iTunes?

So heres the problem. My phone got restored and i lost all of my music and everything. Now i want my music back but it won't work. I tick the sync music box then i click on the sync box and it takes 5 seconds to say 'waiting for sync to start- syncing contacts, waiting for chges to apply' then it is finished. I NEED MY MUSIC!

You actually have to select which files you want to sync. Depending on how much music vs. How much HD space on your iphone, you could sync everything. But its too detail and to much to wright out here is a link hope this helps

Its not a long page. Long story short click on your iphone while it is connected to the computer then go to the top tabs where it says music apps etc. And select the sync tab. This will more than likely give you all that is in your library. If you wanna not have all of your library, you can click specific artist or songs i forget. Or what i like to do is make a playlist of all the songs i want on my phone and just sync my iphone to that folder so anytime you want one song you can just drop it in the playlist and it will begin syncing if connect (cord or wireless)

It this still doesn't work back up phone and restore the phone, then repeat above. Still not working call apple might be a hardware problem instead of a software problem (which we tested with the restore)
