Being a Visual Novel with a theme based on music, The Devil on G-String is bound to have wonderful music.
- Answer, the epic opening theme by Rekka Katakiri, and its remixes:
- The Road To Glory, an absolutely epic remix of "Answer" which is most memorable when it plays during The Reveal.
- The Woman I Love, a beautiful piano remix of "Answer".
- Yuki no Hane, Toki no Kaze by chata is unique and fitting as one of the ending songs.
- Close Your Eyes, the heartbreaking song which plays during the epilogue.
