Big Pun's posthumous release posted a strong first week, but the top of the album chart still belongs to 'NSYNC.

According to sales figures released by SoundScan on Wednesday, the record-breaking boy band sold an additional 533,000 copies of its "No Strings Attached" to hold on to the number one spot on the "Billboard" album chart. The new numbers bring the group's three-week sales total to just under 3.8 million copies.

Santana once again plays runner-up with its "Supernatural," and the week's biggest debut comes in at number three with the arrival of Big Pun's "Yeeeah Baby." The late rapper's album sold more than 179,000 copies in its first week in stores to take the third slot on the chart.

Female Flip Mode Squad rapper Rah Digga also boasts a big debut, landing in the top 20 with her "Dirty Harriet." The rapper moved more than 68,000 of the album in one week to debut at number 18. Other notable debuts include Pink's "Can't Take Me Home" at

26, Stevie Ray Vaughn's "Blues At Sunrise" at 80, the soundtrack to "High Fidelity" at 135, Travis' "The Man Who" at 138, Lou Reed's "Ecstasy" at 183, and M2M's "Shades Of Purple" at 184.

Meanwhile, last week's big debut, the Aaliyah-fueled soundtrack to "Romeo Must Die," continues to go strong, slipping only two slots from three to five on next week's chart.

The week's sales figures also see Sisqo sell an additional 149,000 copies of his "Unleash The Dragon," pushing the album's total sales over the two million mark.
