Ten years ago today, Hilary Duff's Most Wanted was the No. 1 album on the Billboard 200 chart. It was her first compilation, which means it rounded up her biggest hits at that time, including "Come Clean" -- the "Laguna Beach" theme song, you guys! -- and "So Yesterday."

“So Yesterday,” while not a TV show’s intro music, still stood on its own, eventually climbed up to the top of the countdown on TRL and ended up a stone-cold Duff classic. And it still is. As Hilary continues to celebrate the release of latest album Breathe In. Breathe Out., we could think of no way to celebrate, too, than by singing along.

So, how well do you recall the words to "So Yesterday"? Take the quiz below to find out.
