Dead music stars still have major drawing power. Michael Jackson's posthumous documentary and CD 'This Is It' is released this week, and if history is any guide, his estate stands to make a lot of money. Since his death in June, 9 million Jackson albums have been sold -- which means he's already beaten John Lennon and Elvis Presley in his fourth act.

Actors like Marilyn Monroe and Heath Ledger also earned a whopping amount of money after they died. In a dead celebrity shocker, Forbes just announced its list for 2009, with deceased fashion designer Yves Saint Laurent topping the dead celebs at $350 million. (They auctioned off his estate, which contained all his fancy stuff-art, furniture, and clothing.)

MJ debuted at number 3, and the year isn't even done.
