WASHINGTON - Michael Jackson's "Thriller" album is considered important enough to keep for all time.

It's among the 25 recordings added to the Library of Congress' National Recording Registry, which preserves recorded works that are considered culturally or historically important.

This year's additions include "Oh, Pretty Woman" by Roy Orbison and "The Tracks of My Tears" by Smokey Robinson and the Miracles.

Joni Mitchell's "For the Roses" album has been added, as has the original cast recording of "My Fair Lady."

The recordings aren't all music.

Others that have been added this year include the first Trans-Atlantic broadcast from 1925, Harry Truman's speech to the 1948 Democratic Convention and the "Sounds of Earth" disc prepared for the Voyager spacecraft in 1977.
