How to transfer my iTunes library to a new computer?

The original PC with all of the files is HP. I got a Toshiba laptop today and I wanted to sync my music files from the old HP to my Toshiba. I don't want to use my iPhone to transfer any files- resetting it is too much of a hassle and my iPhone only has a small amount of the music actually on it. Could I use a flashdrive to transfer the files?

Now it gets more complicated (maybe.) Once I transfer the files, I want to create a new iTunes account; I've been using my mom's account, but I want my own independent one with my email address, billing, etc. Could I keep all of my files? I'd assume so as long as I'm not using Home Sharing (which I don't really understand anyway.)

If you've gone through this or have an idea, please let me know!

Sure use a flash drive. Depending on the amount of songs you may have to move partial at a time. If you had access to a storage device on a network you wouldn't need the flash drive.

  • Will downloading a new iTunes ruin my old iTunes library? I tried connecting my new iPhone 5 to my iTunes but it said that it wouldn't connect because my version of iTunes was really old (from 2010) and I never updated. It said I need to download a new version of iTunes (10.7 onwards) for it to be compatible with my iPhone. But my question is, IF I download a new version of iTunes, will all my old songs on my old iTunes disappear? Because if I had to re-download my whole library, I would seriously cry. That would take the rest of my life.
  • Transfer iTunes library to a different account on the same computer? My mum hates that my siblings and I put all of our music in her iTunes library because we don't have a computer of our own. I just created a new account on her computer (MacBook Pro) for us, but I can't seem to transfer our songs to that account. Every time I try to transfer the songs from my iPhone (same songs as on my mum's iTunes), it says that they've been transferred but the library stays empty. Any suggestions?
  • How to transfer my itunes library to a new laptop? I have a ton of songs on my iPhone that I want to put on my iTunes Library for my new laptop, but I can't get it to work. Apple support site says to transfer purchases, but I'm not getting that option on the newest version of iTunes. I have already authorized the computer too, so that's not it. I just can't find the transfer option.
