For the first time in nearly a decade, teen acts hold down the top two positions on The Billboard 200. Taylor Swift, 18, opens at #1 with her sophomore album, Fearless. David Archuleta, 17, bows at #2 with his eponymous debut album. This is the first time that teen acts have held the top two spots since January 1999, when Britney Spears, then 17, bowed at #1 with her debut album, ...Baby One More Time, the same week that *NSYNC peaked at #2 with its eponymous debut. Two members of that boy band were teenagers at the time: Justin Timberlake, 17, and Lance Bass, 19.

As for Archuleta, this is the biggest first-week tally for a debut album by an Idol finalist since Season 5 winner Taylor Hicks bowed with sales of 298,000 in December 2006. Last year's winner, Jordin Sparks, debuted at #10 with sales of 119,000 for her eponymous album. Last year's runner-up, Blake Lewis, opened at #10 with sales of 98,000 for Audio Day Dream. (Sparks' album has sold the most of these three. Its stands stand at 953,000.)

Both Swift and Archuleta celebrate birthdays next month. Swift turns 19 on Dec. 13. Archuleta turns 18 on Dec. 28. That means neither had been born was Ronald Reagan was President, Lucille Ball was alive or the Berlin Wall was intact.
