Robert Trujillo is embracing the darkness…

The 58-year-old half-Mexican American musician and his fellow Metallica mates’ single “If Darkness Had a Son,” the latest taste of the hard rock band’s upcoming album, 72 Seasons, debuts at No. 1 on Billboard’s Hot Trending Songs chart dated March 11.

“If Darkness Had a Son” is the third song to be released from 72 Seasons, following the premieres of lead single “Lux Æterna” and fellow promotional single “Screaming Suicide.”

Both songs also made the weekly Hot Trending Songs survey upon release, with “Lux Æterna” reaching No. 6 (Dec. 10, 2022) and “Screaming Suicide” hitting No. 7 (January 28).

“If Darkness Had a Son” debuted on March 1, and thanks to two days of sales and streams, the track concurrently bows at No. 12 on the latest multimetric Hot Hard Rock Songs chart via 1.1 million official U.S. streams and 1,000 downloads, according to Luminate.

72 Seasons, Metallica’s 11th studio album and first since 2016’s Hardwired… to Self-Destruct, is due April 14.
