Alone among newly released titles with strong out-of-the-box sales, Trey Songz’s “Chapter V” handily took the No. 1 spot on the U.S. album chart this week.

The R&B vocalist’s Atlantic set entered at the top with 135,000 copies sold, according to Nielsen SoundScan data for the week ending Aug. 26.

While Songz collected his first No. 1 album and tracked the only six-figure score on the chart, his current number was far from a personal best: His last release, 2010’s “Passion, Pain & Pleasure,” debuted at No. 2 with 240,000 sold.

Amid stagnant dog days for retailers, no title outside the top 10 sold more than 25,000 copies.

Songz witnessed no challenge from last week’s top holdovers, which experienced large sales drops. Last week’s No. 1 debut, rapper 2 Chainz’s “Based on a T.R.U. Story” (Def Jam), slipped to No. 2 with a 48,000-unit frame (down 67%), while the Capitol-distributed “Now 43” hits compilation slid one pole to No. 3 with 45,000 sold (off 40%).

DJ Khaled’s “Kiss the Ring” (Universal Republic) slipped into the top five, reaching No. 4 with a sleepy 41,000 sold. Typifying this year’s prevailing sales patterns, the rapper bested his previous chart position with smaller sales: Khaled’s last album, 2011’s “We the Best Forever,” entered at No. 5 with a 53,000-unit week.

Justin Bieber’s “Believe” (Island) and Maroon 5’s “Overexposed” (Octone/A&M) exchanged chart rungs: Bieber’s album climbed one position to No. 5 despite a 7% drop, selling 32,000, while Maroon 5’s set, trailing Bieber’s by less than 300 copies, dipped 11% and drifted to No. 6.

Owl City – aka bedroom popper Adam Young – landed at No. 7 with his third album “Midsummer Station” (Universal Republic). First-week tally of 30,000 didn’t match the 48,000-unit bow of last year’s “All Things Bright and Beautiful.”

Stanza’s other new top 10 release was Christian act Tenth Avenue North’s “The Struggle” (Reunion). Album’s 26,000-copy debut was strong enough for placement at No. 9.

The week’s other top 10 holdovers included Rick Ross’ “God Forgives, I Don’t” (No. 8, 28,000 sold, down 36%) and One Direction’s “Up All Night” (No. 10, 25,000, off 15%).

One title was conspicuous by its absence in the top 10. With 24,000 shifted, Adele’s “21” (Columbia) sank four positions to No.12 in its 79th week. It’s the first time the British singer’s album, which has sold 9.7 million domestically, has been out of the top 10 since its early 2011 release.
