Reunited pop-punk act Fall Out Boy seemed to have little trouble retaining the old radioactivity, as the quartet’s hiatus-breaking “Save Rock and Roll” bowed at No. 1 on the domestic album chart.

According to SoundScan figures for the week ending April 21, the Chicago act’s Island release moved just under 154,000 units straight out of the box, falling well short of its last No. 1 seller, “Infinity on High,” which sold 260,000 in its first week back in 2007.

The group had to surpass strong chart competition from fellow Midwesterner Kid Cudi. The electro-rapper’s Republic release “Indicud” moved 135,000 units for a No. 2 finish, which was enough to give the Ohioan his album chart peak despite falling short of his 169,000 opening week for 2010’s “Man on the Moon II: The Legend of Mr. Rager,” which topped out at No. 3.

Gotham-based rock trio the Yeah Yeah Yeahs also claimed a career-best chart week, with “Mosquito” (Interscope) landing at No. 5 with just under 38,000 sold.

Among the holdovers, Justin Timberlake’s “The 20/20 Experience” (RCA) declined 22% over the previous week, yet remained in third place with around 76,000 copies sold. Blake Shelton’s “Based on a True Story…” (Warner Bros.) arrived at No. 4 after a 31% decline, and records from fellow country acts the Band Perry and Brad Paisley declined to No. 6 and No. 7, respectively.

Macklemore and Ryan Lewis’ 2012 indie release “The Heist” jumped 14% and returned to the top 10 after notching a tally of 30,000, arriving at No. 9 and falling just a few hundred copies short of Lil Wayne’s “I Am Not a Human Being II,” which fell to No. 8.  Pink propped up the top 10 with “Truth About Love.”

Sales for the previous week’s chart-topper, the self-titled fourth effort from rock act Paramore, dropped 74% to arrive in 12th place.
