T.I.'s T.I. vs. T.I.P. maintains its lead on The Billboard 200 for a second week after moving 175,000 copies in the United States, according to Nielsen SoundScan. That's a 63-percent drop from the album's debut week total of 468,000.

Alternative rock veterans Smashing Pumpkins return after a seven-year absence with Zeitgeist (Martha's Music/Reprise), the chart's top debut at No. 2. The effort sold 145,000 units and ties 1998's Adore as the second best-charting album of the group's career. The double-disc Mellon Collie and the Infinite Sadness bowed at No. 1 on the chart in 1995.

Miley Cyrus's double-disc set Hannah Montana 2 (Soundtrack)/Meet Miley Cyrus (Disney) slips 2-3 this week with 128,000 units, a sales decrease of 32 percent.

Right behind is Interpol's major-label debut Our Love To Admire (Capitol), at No. 4 with 73,000. The rock quartet has had increasing success with each new release: its 2002 Matador debut Turn on the Bright Lights peaked at No. 158 and has gone on to sell 464,000 units, while 2004's Antics debuted at No. 15, selling 63,000 in its first week.

American Idol star Kelly Clarkson's RCA album My December falls 3-5 with 59,000 (-48 percent) while Bon Jovi's Lost Highway (Island) follows suit, descending 4-6 with 55,000 (-41 percent).

Linkin Park's Minutes to Midnight (Machine Shop/Warner Bros.) climbs two rungs 9-7, despite a 4-percent decrease in sales, to 54,000. Meanwhile, Fergie's solo debut re-enters the top tier with the aid of her new single "Big Girls Don't Cry," ascending 11-8 in its 43rd week on the chart with 50,000 (-5 percent). Amy Winehouse's Back to Black (Universal) falls 8-9 with 49,000 (-15 percent).

Indie rock act Spoon scores its highest-charting and best sales week yet with its sixth full-length, Ga Ga Ga Ga Ga. The set debuted at No. 10 with 46,000. The Merge band's only other album to chart on The Billboard 200 was its last, Gimme Fiction, which opened in in 2005 at No. 44 with 20,000. Like that set, Ga Ga enters at the summit of the Top Independent Albums chart.

Pop duo Aly & AJ's Insomniatic (Hollywood) shifts 39,000, enough for a No. 15 entry on the big chart. The duo has charted twice before, first with the studio set Into the Rush (No. 36 in 2005) and the holiday effort Acoustic Hearts of Winter (No. 78 in 2006).

Other big debuts this week include the soundtrack to the upcoming movie Hairspray (New Line) at No. 20 with 37,000, Bad Religion's New Maps of Hell (Epitaph) at No. 35 with 21,000, the soundtrack to Harry Potter and the Order of the Phoenix (Warner Bros.) at No. 43 with 16,000, and Crowded House's reunion set Time on Earth (ATO) at No. 46, also with 16,000.
