I have an Iphone and an Ipod Touch.

I was looking through the music on them assuming it would be the same songs. It wasn't and now my Iphone has 100 songs more

Is there anyway so I can get the 100 songs off and synced so it is exactly the same as my Ipod touch?

I don't really want to be sitting checking songs off it will take a lifetime.

Any help appreciated.

Thanks
