Help, my lappy crashed and I can't sync my iPhone and iTunes

Question

Hi,
Recently my laptop crashed and I had to reformat it. Now when I plug in my iPhone, I think I am going to lose all my mp3s in the iPhone. I don't want to lose the music because I hadn't got the chance to back up the music on my iTunes before it crashed.
Therefore, the music are all inside my iPhone now. How do I re-copy it back into my laptop from my iPhone?
I noticed it is the same for my ringtone, wallpaper and applications as well. I tried to back-up the phone but I dont see the music in my iTunes after I done the back up.
Also, iTunes recognize that this laptop is still authorized.

If you didn't have a backup of your iTunes library, despite all of iTunes warnings that you should back up, you are out of luck for all content that was not purchased from the iTunes store. For purchased content you can use iTunes to recover it from the iPhone. Disable automatic syncing in iTunes, then connect the phone. On the File menu choose "Transfer purchases from <your iPhone's name">. There may be other ways to recover the remaining tracks using unofficial applications. Google is your friend.
