Need iPhone and iTunes

I got a new computer and I'm making a new Apple ID account on the iTunes on my computer. So my Apple ID on my computer is different from my phones. Is there a way i can transfer my music, apps and all that stuff to my computers Apple ID form my phone.

No; also all you purchases will be lost as they are linked to the old account.

Just sign out and sign back in with your old ID. You can have up to six computers authorised on one account/ID.
