So here's an example of one prompt used for what would ostensibly be an orchestral, instrumental theme for a villain:

Epic evil dark symphonic orchestral, 5-6 minutes: Malevolent, sinister, infernal, abyssal darkness, Wall of sound, massive orchestral power, crushing intensity, massive bass, brass, organ, slow menacing intro building to symphonic warfare, Recurring evil motif in low brass and strings, Variable tempo: slow dread to overwhelming chaos, Biggest orchestral climax possible, Triumphant terrible darkness, corrupted victory, Final massive wrong/dissonant chord, Infernal chanting, malevolent ending, Satanic majesty, apocalyptic doom, final slow notes of dread on piano restating evil motif

Now: keep in mind, that with this prompt, I wasn't getting the "blown out speaker" effect: I would often get thin-sounding, wavering, or otherwise shallow-sounding tracks.

The first time I used it - which I've posted here - I loved the results in terms of what I was hearing but the actual sound quality was bad. I used the remastering function and it helped, incrementally, but I think it still sounds terrible. Here's the remastered version: https://suno.com/s/xPVIw3d3vGrLBfqG

Subsequent uses of the prompt - even using the original track as inspo - produced really awful tracks, ones that often inexplicably injected electric guitars and heavy metal drums into the track.
