Joey Fatone probably isn't sweating it, but he and his 'NSYNC counterparts faced the greatest threat to their chart-topping throne this week.

According to sales figures released by SoundScan on Wednesday, 'NSYNC's "No Strings Attached" managed to fend off a charge by Toni Braxton's latest effort to retain the top spot again next week. The boy band's seemingly unstoppable album sold another 248,000 copies last week, sending it well over the 5 million sales mark after six weeks in stores.

Braxton's "Heat" managed to come in a close second (or at least as close anyone else has gotten since 'NSYNC hit the chart) after selling more than 199,000 copies of the album in its first week in stores.

Cypress Hill also managed to crack the top five as the group's "Skull & Bones" moved more than 139,000 copies in one week in stores to debut at number five.

R&B/hip-hop diva-in-training Mya scores a top 20 debut next week as well after selling more than 72,000

copies of her "Fear Of Flying," while folk-rock icon Neil Young makes an impressive debut as well after selling more than 55,000 copies of his "Silver & Gold" to land at number 22.

The week's other notable debuts include Papa Roach's "Infest" at 48, Barry White's "Ultimate Collection" at 148, and the soundtrack to "Where The Heart Is" at 170.

The week's sales figures also brought good news for Eminem, even though his new album won't arrive for another three weeks. With the first single from his upcoming "The Marshall Mathers LP" getting major exposure, Em's last album (1999's "Slim Shady LP") jumps almost 30 chart spots from 62 to 35 this week.
