Thanks to the March 18 release of "Frozen" on DVD and Blu-ray, its soundtrack has scored its best sales week yet. The album spends a seventh week at No. 1 on the Billboard 200, selling 202,000 copies in the week ending March 23 (up 104 percent), according to Nielsen SoundScan. That easily trumps its previous high-water mark, when it shifted 165,000 in the week ending Jan. 5. A week ago, it was No. 1 with 99,000 copies sold.

The "Frozen" album's sales are red hot, owed to buzz generated by the fast-selling home video version of the film. Disney said that 3.2 million units of the DVD and Blu-ray were sold during its first day of release.

It's unusual for an album to log its best sales week so far into its chart life. "Frozen," which was released Nov. 26, 2013, is currently in its 17th week on the chart. Generally, albums start big and then taper off as the weeks tick by.

For example, the last album that was as old as "Frozen" to sell more than 200,000 in a week was Adele's "21," a little over two years ago. In the wake of the 2012 Grammy Awards — where Adele performed and won multiple trophies — "21" sold 730,000 copies (in the week ending Feb. 19). The set had debuted at No. 1 a year earlier, shifting 352,000 copies in the week endingFeb. 27, 2011.

Though "Frozen" just reached DVD and Blu-ray, it's also still in movie theaters. It ranked as the No. 13 highest-grossing film at the U.S. and Canada box office during the March 21-23 weekend (according to Box Office Mojo). Through March 23, it has earned $397 million — the third-highest-grossing film of 2013.

With the soundtrack's additional 202,000 sold, its total sales rise to 1.6 million. Its breakout hit single, Idina Menzel's "Let It Go," recently reached the top 10 on the Billboard Hot 100 and won the Academy Award for best original song.

While "Frozen" continues to be all the rage at the top of the chart, the top 10 also welcomes six new entries.

Rapper YG leads the debut-parade with "My Krazy Life," starting at No. 2 with 61,000 sold. It's the first studio album for the artist, who arrived on the Billboard charts in 2010 with the single "Toot It and Boot It." It reached No. 67 on the Billboard Hot 100. He later followed it up with "My Hitta" in 2013 (No. 19 peak on the Hot 100 and No. 5 on Hot R&B/Hip-Hop Songs) and his current hit, "Who Do You Love." The latter has reached the top 20 on the R&B/Hip-Hop Songs tally and No. 78 on the Hot 100.

Rock trio Foster The People struts onto the Billboard 200 with its second album, "Supermodel," bowing at No. 3 with 54,000. It follows the trio's first album, "Torches," which debuted and peaked at No. 8 in 2011. It has gone on to sell 1 million copies.
