If you would like to register a work that is part of a larger collection, such as a song on an album, you can simply provide the name of the larger collection in your registration. This is how you would do this:
1) Title of Work: List the title of the individual work you are registering here.
2) Title Type - B: List the title of the larger work here. To be clear, you are not registering the larger work in this application.
3) Check the box marked "I am registering each title" to ensure that the individual work, and not the larger collection, is registered.
