Transfer music to iphone 4 to iphone 5?

Its not ITunes Library music, I added them myself. I'm on I tunes the now and just can't figure out how to copy my music over top my new IPhone 5?

You can't use iTunes to transfer music off of your iPod or iPhone. This is in order to help prevent abuse such as sharing music with others.

There's 3rd party software available, which can copy music from your iPod or iPhone to your computers iTunes library; and then you can use iTunes to copy music onto your iPhone 5.

iDump and Sharepod are two good examples of this software, but they are very limited in trial mode. If you have more than 50 songs to transfer, then you'll need to buy the software unfortuantly; they use to be completely free.
