As with all of their albums, Gigahearts maintains the theme of technology and human beings interacting. The album title itself is a play on words of the computer term "Gigahertz" combining with "Hearts". The songs themselves take the same lyrical influences with instrument pieces being influenced by 80s Glam Rock and electronica. Victor Love describes the album as "11 tracks to kick your ass very bad but also to satisfy your desire of melodies and electronic exploration."
