The best part isn't always the chorus
Only 4 of 8 tracks peaked in a chorus. Three peaked in the first 15 seconds, one in the outro. If we had clipped every chorus by habit, we would have posted the wrong 15 seconds for half the album.
Case Study
40 music videos for 8 AI metal tracks — in 22 minutes
Instrumental metal has a video problem: no singer to film, no band budget, and a feed that wants a new clip every day. So we made eight tracks with Suno and ran the whole batch through Songbrain's Suno-song-to-video tool. It found the strongest moment in every track, built a visual world around it and rendered five vertical reels per song. Here is everything it made, plus the numbers behind it.
Full disclosure: Songbrain is built by the same people behind Smoke-Oh. We made it because we needed exactly this.

How it worked
We uploaded all eight tracks as one album. For each one, Songbrain first listens to the whole song: genre, energy, structure, and where the track actually hits hardest. Its hook finder ranks every candidate moment, so the reels start on the part that grabs people instead of on a slow intro.
Then it writes a short "world" for the song from its mood — for Doomsday Calling that was a decaying automated facility full of warning lights — and generates images that fit it. Those get cut to the beat and rendered in five formats, from a full storyboard reel to an audio-reactive visualizer. We didn't write a single prompt or open an editor.
All 8 storyboard reels
One reel per track, each starting at the moment Songbrain ranked highest. Sorted by virality score.
One song, five looks
The point of five formats is posting rhythm: one track can carry five days of posts without the same clip twice. Here is everything that came back for Big One, the highest-scoring track.
The numbers
Every track also got a full analysis, including a virality score for Suno songs that rates how well a track is built for short-form video. This is what the batch looked like.
| Track | Style | Length | Score | Best part | Visual world |
|---|---|---|---|---|---|
| Big One | Cinematic | 2:35 | 88 | 0:13 (Intro) | A vast cavern, harsh light, low mist |
| Soul King | Metalcore | 3:40 | 81 | 1:25 (Chorus) | A smoky arena stage with fiery red accents |
| Violin Metal GODs | Metalcore | 3:38 | 79 | 1:49 (Chorus) | An industrial concert stage in coloured haze |
| Perfect Duo | Heavy Metal | 1:50 | 79 | 0:09 (Intro) | Industrial landscape under a smouldering sky |
| Genesis | Heavy Metal | 3:40 | 78 | 1:34 (Chorus) | A cavernous ruin in dim twilight |
| Doomsday Calling | Metalcore | 3:39 | 76 | 2:46 (Outro) | A decaying automated facility, warning lights |
| Phonk Violin | Thrash Metal | 3:18 | 73 | 1:30 (Chorus) | An industrial ruin under an electric storm |
| Strings Of The Fallen | Heavy Metal | 3:14 | 73 | 0:06 (Intro) | A rust-coloured wasteland, desaturated sky |
What we learned
The top scorer gets to the point
Big One scored 88, the highest of the batch, and its strongest moment lands at 0:13. The four tracks that make you wait 1:30 or longer for the payoff scored 73 to 79. An early peak alone isn't enough though: Strings Of The Fallen peaks at 0:06 and still scored 73.
One upload, five days of posts
Five formats per track means a single song covers five days of daily posts without repeating a clip. For eight tracks that's 40 posts, rendered in 22 minutes.
What didn't work perfectly
The worlds got repetitive. Six of the eight tracks ended up in some kind of industrial ruin or dark stage. That fits the music, but side by side it's a lot of rust. Songbrain lets you re-roll single storyboard images, which is what we'd do before posting the whole album in one week.
The violin didn't always register. On Phonk Violin the analysis heard thrash metal and no violin at all; it only picked up strings on Soul King and Big One. Heavily processed AI strings sitting under distorted guitars are hard to separate, so if your genre lives on an unusual lead instrument, check the genre tag before you trust it.
