Can't put music from iTunes to iPhone?

Ok so i can't seem to drag my music in my library to my phone, when i drag it, it goes in but it doesn't say sync or anything and when i look on my phone it didn't go on! I've transferred music before and all of the sudden one day it just stopped working.someone help?

So you drag music from a library to iTunes? Well if that's the case it might be a file not recognized.

Try reinstalling iTunes. If that doesn't work make sure your iPhone isn't full.

I think if you are facing serious problems with iTunes. You would find it easier to use a simple alternative. Just download iTools to transfer & put music on your iPhone from your pc.
