Logo for Andrew Hussie's Homestuck
Homestuck is the fourth MS Paint Adventure, an installment in the webcomic series by artist and writer Andrew Hussie. Homestuck is by far the longest installment in the series, after the third MSPA, Problem Sleuth, as well as the most popular and widespread.
Most of the music discussed on this wiki was inspired by and/or written for Homestuck, excluding works for other MSPA, Hussie's non-MSPA works, and non-Homestuck music written by prominent Homestuck musicians. Even including these, Homestuck, through its incorporation of an original soundtrack for its flash animations, long runtime, large fandom and significant creator/fandom interplay (nearly all Homestuck official musicians and other collaborators were sourced from the fandom), is responsible for creating the phenomenon, canon and community of Homestuck and MSPA Music (HaMM) that this wiki discusses.
It's why we're here, folks.
