Multiple iTunes Libraries

This feature, beginning with iTunes 9, allows you to create multiple iTunes Libraries in the same Login Account. Great for when you share an account among several people, each with their own connected devices, and would rather that everyone have unique libraries.

And it's easy to set up.

Similar to holding the Option key when you start up your Mac to choose between different booting cycles iTunes will create a fresh new empty Music Library. Simply give it a name and begin building your new library.

If you forget to hold the Option key when you open iTunes it defaults to the last library opened.

iTunes is available for Mac and Windows.
