Transferring iPhone data to new MacBook

I recently got a new MacBook, and want to transfer the music and data from my iPhone to this mac.
I usually back my phone up with my account on our family desktop Mac, but now I have my own and want to get my phone songs on my laptop iTunes.
I happened to e-mail myself a couple of songs from my desktop to my laptop, and I hope that's not a problem.
Can you tell me what I can do to transfer my iPhone data to my new laptop that already has some e-mailed songs?

Well, it's very easy to transfer iPhone data like music, photos, music, etc to Macbook with 4Videosoft iPhone to Mac Transfer Ultimate. It will not sync your iPhone to macbook, while you decide which files to transfer to laptop.It'll not erase anything from the computer. You can search it on the website and have a free try.
