Katy Perry Celebrates an Entire Year in the Top 10

Frazer Harrison/Getty Images(NEW YORK) -- The success of Katy Perry's album Teenage Dream has allowed her to set record after record, and now here's another one: this week, she becomes the first artist in the history of the Billboard Hot 100 to spend 52 straight weeks -- a whole year -- in the top 10, with releases from her album.

Katy's year-long streak started last May when her single California Gurls debuted at #2.  The song went on to spend six weeks at #1.  Then, in August, her second single, Teenage Dream, entered the top 10.  It went on to top the charts for two weeks. In November, just as Teenage Dream dropped out of the top 10, Firework replaced it.  It went on to spend four weeks at #1.  And in March, when Firework was still in the top 10, her current #1 hit, E.T. joined it there and hasn't left since.

Prior to Katy setting her record, the previous one was 48 straight weeks in the top 10, set by the Swedish pop group Ace Of Base.  Ironically, Katy has cited Ace of Base as one of the inspirations for the sound of Teenage Dream.

Lady Gaga Stays at #1 for a Fourth Week, 'Poker Face' Passes Six Million in Sales

ROBYN BECK/AFP/Getty Images(NEW YORK) -- Lady Gaga's hit Born This Way was born to be a chart-topper -- ever since it debuted at #1 a month ago, it hasn't relinquished that position at the peak of the Billboard Hot 100.  According to Yahoo!'s Chart Watch column, it's the first song by a female solo act to debut at #1 and then stay there for four weeks since Mariah Carey's Fantasy.  That Mariah song eventually went on to spend eight weeks at the top; it remains to be seen if Born This Way can do the same.

In other Gaga news, one of her previous hits, Poker Face, has just passed the six million mark in digital downloads.  Only three songs have ever sold more than six million copies, and two of them are by Gaga: Poker Face and Just Dance.  The other one is The Black Eyed Peas' I Gotta Feeling, which has sold more downloads than any other song in history.

In addition, "Only Girl" becomes Rihanna's ninth number one hit overall.  She's now scored the most number ones of any artist since the year 2000.

Additionally, this marks the first time in the history of the Hot 100 that an album's lead single has hit number one after the second single has already done so.  Rihanna's "What's My Name" overtook "Only Girl" to land the top spot a couple weeks ago.

Meanwhile, Rihanna's new CD Loud enters the Billboard chart at number three, with first-week sales of 207,000 copies, according to Nielsen Soundscan.  That's the most any of her albums have sold in a single week.  Loud is Rihanna's fifth top 10 album -- all her previous albums have reached the top 10, as well.
