Thank you. It took some tinkering to get it just right. I created the instrumental melody from a voice recording to guide the sound. I then did a first pass in Suno to first get the instrumental to sound similar to the score in the Dexter series, then covered that in a new style to apply a cinematic alt rock vibe to it, but blended with the original style. Lastly I added the vocals, which is a new feature in Suno where you can add vocals to an existing instrumental.
It's a "tribute" to the Dexter TV show, so I wrote the lyrics from the perspective of his "Dark Passenger" which in my mind would be a seductive female voice and there's a string section in the song that plays homage to the "Blood Theme" from the soundtrack.
