Phillip Phillips' "Home" tops the 2 million mark in digital sales this week. This marks the first time that an American Idol winner's "coronation song" has sold 2 million copies. The previous best-seller among coronation songs was David Cook's "The Time Of My Life," which has sold 1,463,000 copies.

"Home," which has the rootsy appeal of Mumford & Sons, entered the Hot 100 at #10 in June, the week after Phillips was crowned the Season 11 winner. It then tumbled down the chart until NBC featured the song during its coverage of the Summer Olympics in August. The week after it was featured on the Olympics, it rebounded from #84 to #9.

Taylor Swift's "I Knew You Were Trouble," the fourth "preview track" from her upcoming album Red, sold 416K copies in its first week. It's Swift's second song to sell more than 400K copies in its first week. "We Are Never Ever Getting Back Together," the first preview track from Red, sold 623K copies in its first week eight weeks ago. Swift is the first artist in digital history to have two songs that debuted with sales of 400K or more copies.

Here's another way of saying pretty much the same thing: Just 10 songs in digital history have sold 400K or more copies the first week out. Swift is the only artist with two of them.

One Direction's "Live While We're Young," the first single from the U.K. boy band's upcoming sophomore album, Take Me Home, is the top new entry on the Hot 100 at #3 (just behind Maroon 5's "One More Night" and PSY's "Gangnam Style"). "Live While We're Young" is the first song by a boy band to enter the chart inside the top five since Jonas Brothers' "Burnin' Up" debuted at #5 in July 2008.

"Live While We're Young" is One Direction's highest-charting hit to date, surpassing its breakthrough smash "What Makes You Beautiful," which peaked at #4 in April. It's vying to become the first song by a boy band to top the Hot 100 since *NSYNC's "It's Gonna Be Me" headed that chart for two weeks in the summer of 2000.

"Live While We're Young" enters Hot Digital Songs at #1.  It's the first song by a boy band to top the digital chart (which originated in June 2003, two months after the opening of the iTunes store). "Live Like We're Young" sold 341K copies in its first week. That's the biggest

Last week, you'll remember, Mumford & Sons' Babel trounced new albums by such heavyweights as Green Day and No Doubt. This week, Babel stays on top of The Billboard 200 for a second week, but the big surprise is that Green Day's Uno! and No Doubt's Push And Shove both drop out of the top 10. Uno! drops from #2 to #11. Push And Shove drops from #3 to #13.

It's increasingly common for albums to fade quickly after big (or even not-so-big) first weeks. Of the five albums that debuted in the top 10 last week, only Babel remains. Albums by Lupe Fiasco and Deadmau5 also drop out this week.

This is particularly bad news for Green Day and Lupe Fiasco, whose albums have sequels scheduled for release. If the first installment drops out of the top 10 after one week, that doesn't exactly bode well for the series.
