Amid midsummer album sales doldrums, the “Guardians of the Galaxy: Awesome Mix Vol. 1” soundtrack maintained its chart-topping position as compilations ruled the roost on the U.S. rolls last week.

Hollywood Records’ companion to the Disney/Marvel superhero hit held the No. 1 post for a second consecutive week with sales of 93,000 (down 15%), according to Nielsen SoundScan data for the week ending Aug. 17. The title comprises ‘60s and ‘70s rock and pop hits.

The “Now 51” hits compilation also remained lashed in at No. 2, moving 52,000 (off 45%) in its second chart week, while Disney’s “Frozen” soundtrack bounced up five positions to No. 3, shifting 43,000. The latter album previously logged the longest stretch at No. 1 for any title this year, claiming the apex for 13 weeks; it received a large bounce in its 38th chart frame thanks to sale pricing at the iTunes store.

Two new releases climbed aboard the top 10 with comparatively tepid first-week performances. New Jersey rock quartet the Gaslight Anthem arrived at No. 4 with its fifth studio album “Get Hurt” (Mercury), launching with 33,000 units sold. The band logged its best performance to date with its previous album “Handwritten” (2012), which bowed at No. 3.

Actor-singer Troye Sivan collected the No. 5 position with his EP “TRXYE” (Decca), which rang up 30,000 copies. Best known in his native Australia, Sivan has stoked interest in his music via posts on YouTube.

The chart was filled out by “Five Seconds to Summer” (No. 6, 27,000 sold, down 24%), Sam Smith’s “In the Lonely Hour” (No. 7, 26,000, off 3%), Godsmack’s “1000hp” (No. 8, 21,000, off 63%), Tom Petty & the Heartbreakers’ “Hypnotic Eye” (No. 9, 20,000, down 41%) and Luke Bryan’s “Crash My Party” (No. 10, 19,000, up 19%). Bryan’s title also gained via iTunes sale pricing.
