"Infinite" is Infinite's theme song in Sonic Forces, serving as a "counter-theme" to the main theme "Fist Bump". It was composed and arranged by Tomoya Ohtani, with lyrics and performance by Tyler Smyth and Andy Bane of the metalcore band Dangerkids. A mix of dubstep, trap, and metal, the song is written from Infinite's perspective, and is fittingly full to the brim with egotistical boasting and dreams of power. It also leaves cryptic hints as to the nature of his power.
