Susan Boyle also topped the British album sales charts earlier this week. Boyle’s album sold a record-setting 701,000 copies sold, even beating out American Idol alumni Adam Lambert‘s debut album, which came in at number three. Andrea Bocelli‘s My Christmas took the number two spot.

I Dreamed a Dream slugged out Eminem‘s previous record sales this year for Relapse, making it the biggest debut album of 2009 by far.

In a week that featured new albums by Lambert, Rihanna and Lady Gaga, pulling the number one spot is quite a coup for Susan Boyle.

Susan Boyle, who became an international phenomenon after her audition on Britain’s Got Talent, only ended up finishing second place in the competition. But winning a TV reality competition is a pale victory compared to topping an album sales chart when your CD isn’t even going to be out for another three months.

Susan Boyle’s debut album, I Dreamed a Dream, has blown away everyone from Whitney Houston to the Beatles on Amazon.com, even though her album is only currently available for pre-order. That’s got to hurt a bit for poor Whitney, whose new comeback album just came out this week.

Susan Boyle managed to top the Amazon.com bestseller list despite the fact that very little is known about the contents of her new album. The sum of what we know so far is what Britain’s Got Talent and American Idol judge Simon Cowell thinks about the recording. “She sounds fantastic on record,” Cowell told People. “She’s so good, the album is not just going to be show tunes. We’re going to take our time with this.”

Boyle’s debut CD is due to be released on November 24, just in time for the holidays.
