After a five-year absence from The Billboard 200, UGK returns to the tally in a big way as Underground Kingz debuts at No. 1. The hip-hop troupe's first chart-topper, the Jive set moved 160,000 copies in the United States, according to Nielsen SoundScan, the best sales week ever for UGK and its members, Bun B and Pimp C. UGK's previous charting and sales best came with 2001's Dirty Money, which bowed at No. 18 with 98,000.

Fueled by its popular single "Shawty" featuring T-Pain, Plies' Slip-N-Slide debut Real Testament enters at No. 2. The rapper's album sold 96,000 units; "Shawty" has peaked at No. 12 on the Hot 100 thus far, and was last week's biggest airplay gainer.

The NOW 25 hits compilation keeps the No. 3 spot warm on the big chart for a second week, selling 86,000 with a 30 percent sales decrease. Despite an 8 percent sales slip, Miley Cyrus' Disney double-disc set Hannah Montana 2 (Soundtrack)/Meet Miley Cyrus climbs a slot 5-4 with 75,000.

The Jonas Brothers' self-titled sophomore record shifted 69,000 copies to debut at No. 5 on The Billboard 200. Jonas Brothers is the first album to be issued in the CDVU+ format. The packaging features 100 percent recycled paper and the CD unlocks photos, lyrics, and liner notes when inserted in a computer. The pop-rock group's first effort, 2006's It's About Time (Columbia), bowed and peaked at No. 91.

The New Line soundtrack to Hairspray falls 4-6 with a 16 percent sales decrease to 69,000, a few hundred short of the Jonas Brothers' sum. After bowing on top last week, Common's Finding Forever descends to No. 7 with 58,000, a 63 percent sales hit.

Fergie's The Dutchess (will.i.am/A&M/Interscope) climbs 9-8 with 52,000 (-3 percent), flip-flopping with T.I.'s Grand Hustle/Atlantic set T.I. vs. T.I.P. (8-9, 45,000, -18 percent). Korn's Untitled (Virgin) slips 2-10 with 39,000 after a 64 percent sales decrease.
