FLASH POINTS

• Nas scores his fifth No. 1 album on the Billboard 200 as his new untitled effort starts in the penthouse with 187,000. It's the follow-up to his 2006 No. 1 set "Hip Hop Is Dead," which started with 354,000 during Christmas week. Last week marked the first time since 1999 that Nas released a new studio set outside of the fourth quarter. Nas has also rang the bell at No. 1 with 1996's "It Was Written," 1999's "I Am . . . " and as part of the 1997 self-titled Firm supergroup album . . . Last week's No. 1, Lil Wayne's "Tha Carter III," slips to No. 2 (105,000; down 15%).

• The "Mamma Mia!" soundtrack jumps to No. 3 with an 89% increase in sales, shifting 91,000 this week. The film bowed in U.S. theaters last Friday (July 18) and earned the highest-grossing weekend opening for a musical. The film of course is based on the stage musical "Mamma Mia!" and the music of ABBA. The group's presence is very much felt all over the charts this week thanks to the movie's boffo bow. The act's "Gold -- Greatest Hits" rises to No. 1 for the first time on Top Pop Catalog (15,000; up 96%) while the group is also at Nos. 13 and 24 with two more compilations. Additionally, the original cast recording of "Mamma Mia" zooms 47-8 on Top Pop Catalog (6,000; up 92%) and is a mere handful of units away from the No. 1 slot on Top Cast Albums.

• John Mellencamp grabs his fourth top 10 debut as "Life Death Love and Freedom" starts at No. 7 with 56,000. It's his 19th charting album overall, stretching back to the Aug. 18, 1979, debut of "John Cougar" ... David Banner plants the flag at No. 8 with his third straight top 10 studio album, "The Greatest Story Ever Told," shifting 52,000 ... Taylor Swift bows at No. 9 with her Wal-Mart exclusive EP "Beautiful Eyes" (45,000). On Top Country Albums, it starts at No. 1. She also happens to be No. 2 on the Country Albums chart with her self-titled debut, making it the first time the top two slots on the Top Country Albums chart are owned by the same artist since LeAnn Rimes did the trick in 1997.

• Country veteran Randy Travis snares his highest-charting album on the Billboard 200 as "Around the Bend" debuts at No. 14 with 31,000 -- his best sales week since 1992. Over on Top Country Albums, it begins at No. 3, his highest rank since 1991 when "High Lonesome" peaked at that spot. Travis played "Late Show With David Letterman" (July 15) and "Good Morning America" (July 16) during release week.

• Other debuts landing on the Billboard 200 this week include . . . a new chart peak for O.A.R. as the band returns with "All Sides," its first studio album since 2005 (No. 13 with 33,000) and the soundtrack to "The Dark Knight" (No. 20 with 25,000). Also, the Hold Steady re-enters the chart at No. 30 with "Stay Positive" after the album was released physically last week. It had been available only in digital for the past month.
