What happened to the Jonas Brothers’ unstoppable sales power? Their new album, Lines, Vines and Trying Times, opens in the top spot on this week’s Billboard 200 chart after selling 247,000 copies, according to Nielsen SoundScan. That’s a perfectly respectable number for a young act, and it was plenty enough to unseat last week’s winners, the Black Eyed Peas. Yet consider that the JoBros’ previous proper album shifted a hefty 525,000 in its first week — not in some long-gone commercial utopia, but last summer. And this year, the Peas, Dave Matthews Band, U2, and Eminem have all had no trouble topping the 300,000 mark. The Jonas Brothers clearly still have a devoted fan base, and they have decades ahead of them to continue expanding their audience the way those much more established artists have. But it seems like high time to start thinking of the Brothers as a solid mid-sized act instead of a sales juggernaut, at least for now.

Elsewhere on the chart, Incubus’ greatest-hits set Monuments and Melodies moved 70,000 units to come in at No. 5. And that was it for Top 10 debuts this week. So what do you think of the Jonas Brothers’ chart performance? Is this just a fluke, or are their blockbuster days already gone for good?
