Megalovania was composed by Toby Fox, first appearing in Homestuck around 2010 and later becoming the infamous boss theme for Sans in Undertale's Genocide Route in 2015. Its relentless melody made it one of the most remixed video game tracks on the internet, spawning chiptune covers, orchestral arrangements and endless memes. This orchestral version leans into that legacy, giving the tune a symphonic scale that fits dramatic edits and gaming compilations, which is why the track keeps circulating on soundboards years after release.
