My first thought a while back was that the mods done by adrdesign had more impact, just a lot more snappy. Writing my mod I was mostly conscious of it not becoming boring and arriving at a point where it would loop nicely somewhere close to 100kb. Perhaps that lends it better to being an in game tune as adrdesign said. But you da boss.
Re. my mods - it's completely up to you. Maybe the dissonance in V7 has a certain charm lacking in the V8 guitar version, or maybe my ears can't tune anything for shit!
