If you think about it, the soundtrack to “Juno” — the sleeper film that’s now been nominated for a Best Picture Oscar — has no business being Billboard’s best-selling album. After all, it is a collection of songs from a number of relatively unknown and largely underground artists, musicians like Kimya Dawson, Sonic Youth, Belle and Sebastian and the Moldy Peaches.

“I never looked at charts in my life,” Dawson told MTV News earlier this month. “I’m not interested in being with a major label, I just make music and play shows. And I live in Washington State, which I like because there, people play music because they like music. [The attention from 'Juno' is] “All just weird,” she continued. “I’m mainly happy about it because I love the movie ‘Juno’ and I’m happy to be a part of it.”

Yet, somehow, the record has managed to surpass a mega-star like Alicia Keys and assume the chart’s peak position with a mere 64,800 copies. Released seven weeks ago, the LP failed to chart initially, selling just 4,700 units. But in truth, it was only a matter of time before “Juno” reached the top. Four weeks ago, the soundtrack came from out of nowhere, entering the top 200 for the first time at #8 with sales reported at 38,000. The week after that, it climbed to #3 and then, the following week, to #2. It’s been a slow and steady ascension for the soundtrack, which bumps Keys’ As I Am, which scanned 59,800 copies, to #2, making “Juno” the nation’s new chart-topper, according to the latest SoundScan totals.
