It probably surprises you as much as it surprises us (very little), but the Jonas Brothers have debuted at No. 1 on this week's Billboard 200 chart. "Lines, Vines and Trying Times" moved 247,000 copies, thought the trio's last studio album "A Little Bit Longer" bowed with 525,000 last August. "Lines" is the brothers' second chart-topper, hard to believe it. The soundtrack to their 3D movie only peaked at No. 3 earlier this year.

Black Eyed Peas' "The E.N.D." slips to No. 2, with sales down 51% to 148,000, pushing Dave Matthews Band's "Big Whiskey And The GrooGrux King" to No. 3 with 88,000 (-31%). Eminem's "Relapse" follows suit, falling 3-4 with 72,000 (-17%).

"Monuments and Melodies," the first greatest hits set from Incubus, debuts at No. 5 with 70,000 copies. This release is a double-disc deluxe version, with the regular version due on July 21.

Lady GaGa holds tight to No. 6 with "The Fame" (47,000, flat sales) as Chickenfoot's self-titled album slips 4-7 (43,000, -46%). Moving 7-8 is the soundtrack to "Hannah Montana: The Movie" with 42,000 (-9%). Green Day's "21st Centruy Breakdown" falls 8-9 with 40,000 (-3%). Climbing a notch, Taylor Swift's former chart-topper "Fearless" re-enters the top tier 11-10 with 38,000 (+10%).

This week of sales is up 6.5% compared to last week's sales, though is down 18.5% when compared to the same week last year. Sales totals for the year are down 14.6% compared to the same sum last year.
