This article explains how to transfer iTunes purchases to someone else using a web browser.
Reassigning an iTunes Account
Here's how to reassign your iTunes account by changing the account details for your Apple ID. It's possible to make these changes using just a web browser.
Go to the My Apple ID website in a browser.
Enter your Apple ID and password in the appropriate fields.
If you have two-factor authorization enabled, you'll be asked to enter a six-digit security code sent to another one of your devices.
In the Account, Security, Devices, and Payment & Shipping sections, select Edit. Change the information to that of the person who will now own the Apple ID.
After changing the email address, you may be required to verify the change before it takes effect.
The person to whom you reassigned the Apple ID now has complete ownership and control over the iTunes music you purchased in the past, as well as everything else affiliated with your Apple ID.
It isn't possible to transfer ownership of your music because every song purchased from the iTunes Store is linked to a particular Apple ID, which cannot be changed.
Why Reassign Your iTunes Account?
It's easy to share your iTunes music library with your family by using the Home Sharing feature. But if you switch to another streaming service and will no longer use your iTunes account or listen to the music in it, it isn't possible to transfer ownership of that digital content to another Apple ID, such as your partner's or child's Apple ID.
There is a workaround, however. If you change the account details for your Apple ID, you can effectively assign it to a different person. That person will then have ownership over your iTunes music library.
When you change the account details for your Apple ID, the ID itself doesn't change, but the details behind it do. This lets the new owner use their email address, set up credit card information, and authorize computers and devices.
Before you take these steps, realize that everything in your past or present that is tied to that Apple ID is about to leave your control. If you are transferring it to a close family member, that may be OK with you. If you aren't comfortable with that prospect, don't reassign the account.
You won't be able to access this Apple ID in the future.
