The Slim Shady LP, Eminem's major label debut, made Mr. Shady a huge star.

Since its release in 1999, the project has sold close to 20 million copies worldwide.

Em's about to add some to that total.

To celebrate The Slim Shady LP's 20th anniversary, Em just re-released the album on streaming services with some bonus tracks.

The two completely new tracks on the album "Get You Mad "and "Bad Guys Always Die," from the Wild Wild West Soundtrack, were already known by most of Em's fans.

It's unclear if there will be  a physical release of the reissue.
