And it's not just Courtney that clearly likes Meshuggah, because Mike writes and plays the riffs. "The Beauty of Suffering" is pretty obviously inspired by "Bleed" in parts. I've never been able to get into Jinjer myself, but Spiritbox, Red Handed Denial, Destiny Potato/Sordid Pink, and Morphide give me the feelings that I suppose that band gives other people.
Picking songs on Eternal Blue is really hard, over half of it was probably my favorite at one point or another (though half of the singles were my least favorites), but it's between "The Summit", "Eternal Blue", "Sun Killer", and "Hurt You" these days.
I should also add, I probably ignored them for a long time because I did not like the early releases of iwrestledabearonce with a different vocalist. They felt like a gimmicky joke/meme band and not really worthy of serious listening. I was out of the music news loop when Courtney and Mike took over that band, but wouldn't have paid any attention anyway. But Spiritbox is very different, far more melodic and atmospheric, and the chaos is much more controlled.
