Get up and Fight

Muse frontman Matt Bellamy met Swedish hitmaker Shellback (Maroon 5's "Moves Like Jagger," Taylor Swift's "I Knew You Were Trouble") in LA and they talked about doing a song together for Simulation Theory. This pop banger was the result.

Tove Lo contributes some backing vocals to this rally cry. The singer came on board through her fellow Swede Shellback. Bellamy told The Sun that both the Scandinavians "used to be metallers" in their younger days, and that Shellback had even attended a Muse show back in 2001 in Sweden. "When I met him, he told me he'd even been in the mosh pit," he added.
