James Hetfield of Metallica wants Motorhead in the Rock and Roll Hall of Fame — and sooner rather than later.

Rolling Stone reports that he told a radio interviewer that Lemmy’s passing has made it “really, really important” for him to “see Motorhead acknowledged.” He says “there’s no more rock and roll person on the planet than Lemmy.”

The song “Murder One” on Metallica’s upcoming Hardwired…to Self-Destruct album is about the bass-playing frontman. “To see your idol, your immortal one, actually be mortal…hit us pretty hard,” Hetfield said. “So I felt lyrically it makes sense to acknowledge him and how much he’s meant in our lives.” Murder One was the name of Lemmy’s favorite stage amplifier.

Hetfield calls Lemmy, who was born Ian Kilmister, “such an icon [and] such an inspiration to Metallica” that there’s “certainly no way [they’d] be around if there was no Motörhead.”

Asked at April’s Rock Hall induction which bands deserve to be in that aren’t yet, Hetfield’s bandmate Lars Ulrich also put Motorhead at the top of the list.
