APPLE ITUNES ACCOUNT SWITCH

I've been on my dads Itunes account since I got my first ipod, but now I need to switch all my music over to the new account I just made for myself. How do I transfer all my old music to my new account? I have it all on my ipod (which is an old Iphone without the sim card).

Added (1). Don't be a d***. I have no issue with my dads music. And my music and his music were separate in the accounts. I'm going off to college soon and need my own account, a**hole.

Step 1. Close your eyes
Step 2. Take a ***
Step 3. Eat your ***
Step 4. Your dads music will be on your account!
