He may be more of an R&B/funk singer, but Bruno Marsis making his mark in the rock world…

The 33-year-old part-Puerto Rican Grammy-winning singer’s rockin’ collaboration with Ed Sheeran and Chris Stapleton “Blow” debuts at No. 3 on Billboard‘s Hot Rock Songs chart dated July 20. 

It’s Mars’ first-ever appearance on the rock chart.

The closing track from Sheeran’s album No.6 Collaborations Project, released on July 12, opens with 7.5 million U.S. streams, 1.5 million in radio reach and 26,000 downloads sold, according to Nielsen Music.

The sales sum also sparks the cut’s No. 1 debut on the Rock Digital Song Sales chart, marking each artist’s first leader. Sheeran is the only member of the trio with a prior history on the tally, having reached a previous No. 3 best with “Lego House” in 2013.

“Blow” also bows at No. 40 on the Mainstream Rock Songs airplay chart, a first for Sheeran and Mars.

On the all-format, streaming-, airplay- and sales-based Billboard Hot 100 (the same formula employed by Hot Rock Songs), “Blow” begins at No. 60.
