Mostly when I work out, I'm either listening to the album Nemesis by Stratovarius or just about anything by Sabaton. Right now it's the Art of War album by Sabaton on repeat
Artists I've enjoyed working out to: Devo, The Screamers, Liquid Liquid, Cabaret Voltaire, Stephen Mallender, Pere Ubu, Einsturzende Neubauten, Young Marble Giants, Sex Gang Children.
