MC Lars - This Gigantic Robot Kills
Get some DEVO in there.
Watch who you’re calling a flesh creature, there, buddy.
Who’re you calling a buddy, friend?
Down in the Park - either the original Gary Numan version of the Foo Fighters cover.
Come to think of it, lots of Gary Numan songs could probably work.
Gates of Steel - Devo
A man is real
Not made of steel!
Dismantled - Armed and Ready
Front Line Assembly- tons, but mostly the Hard Wired album (Circuitry is a good example) and also the track Search and Destroy from the Millennium album. Most of their catalog is basically a musical sci-fi movie.
Obligatory link to Muse’s “Supermassive Black Hole” live at Wembley Stadium (with the funky marching CGI robots on the big screens). Although the lyrics themselves have no robot references, Matt’s XY screen solo is itself very futuristic and high-techy.
