Sound

Introduced in Homestuck, the [S] command prefix indicates when a page has sound. While not conventional for a webcomic, this nonetheless means that epic moments are accompanied by equally epic music.

Soundtrack
There are many different arrangements in Homestuck, used for Haunting Solos, Background Music, and Casual Listening. As such Andrew Hussie has set up a Sound Credits Page. The listing by mixes is as follows. The songs can also be downloaded here.
