A release during the usually quiet Fourth of July week didn't deter sales of T.I.'s T.I. vs. T.I.P., which sold 468,000 copies in the United States, according to Nielsen SoundScan, to debut at No. 1 on the Billboard 200.

Another sophomore set bows inside the top tier this week as Kelly Rowland's Music World/Columbia set Ms. Kelly debuts at No. 6 with 82,000. The former Destiny's Child singer was last on the chart in 2002, when her solo debut Simply Deep entered and peaked at No. 12 with 77,000.

Brad Paisley's 5th Gear (Arista Nashville) moves from No. 5 to No. 7 after a 27 percent drop to 59,000, while Amy Winehouse's Back to Black (Universal) falls from No. 6 to No. 8 with 57,000 (a 9 percent slide) in its 17th week on the chart.

Linkin Park's Minutes to Midnight (Machine Shop/Warner Bros.) descends from eighth spot to No. 9 with 57,000, a 1 percent decline. The White Stripes' Icky Thump (Third Man/Warner Bros.) is down from No. 4 to No. 10 after a 37 percent sales slide to 56,000.
