What Pumpkin

The 2009 webcomic Homestuck, written and drawn by Andrew Hussie, currently holds a soundtrack consisting of 27 digital albums. Besides static images, Homestuck makes use of flash animations and games, which often involve background music. The music of Homestuck is composed by fans, but is published by Hussie through his Bandcamp page under the What Pumpkin record label. Hussie established a small "Music Contribution Team" for the webcomic, which is coordinated by Toby Fox.

The first piece of music ever featured on MS Paint Adventures was a fan-made title theme for Problem Sleuth, created by later-Slender: The Eight Pages-developer Mark J. Hadley. While starting Homestuck, Andrew Hussie posted an open invitation for composers on the MS Paint Adventures forums. Clark Powell, the creator of the "Homestuck Anthem", responded to this call, becoming a member of the "Music Contribution Team". Jeremy "Solatrus" Iamurri's work on Homestuck's music gave him the exposure needed to become a professional musician.

After he posted various piano covers on a Homestuck fan forum, Hussie reached out to Toby Fox – who later went on to create the video game Undertale – to produce music for the webcomic's flash animations. The song "Megalovania", which Fox initially composed for an EarthBound ROM hack titled The Halloween Hack in 2008, was used in Homestuck as well as Undertale. Fox recounts that he set a goal for himself to get his music featured in the webcomic, predicting the direction the story would take and sending in music that would be relevant in the predicted situations. In an interview with Polygon, Fox said that "Over time I kind of established that I 'get' what [Hussie] wants pretty well," which eventually led him to the role of production coordinator for music.
