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% sales decrease. Despite an 8% 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% 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% 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% sales hit.

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

Other big chart debuts this week include Fuel's sixth effort, "Angels & Devils" (Epic, No. 42, 15,000), Slightly Stoopid's "Chronchitis" (Stoopid, No. 55, 12,000), Kat DeLuna's debut album "9 Lives" (Epic, No. 58, 11,000), Okkervil River's Billboard 200 debut "The Stage Names" (Jagjaguwar, No. 62; 10,000) and Drowning Pool's "Full Circle" (Eleven Seven, No. 64, 10,000).
