Sheet Music Boss is an Australian YouTube channel that was started by Samuel Dickenson and Andrew Wragnell on February 4, 2017. They create piano covers for various songs, with the addition of original music. Both Samuel and Andrew compose music for the channel, whereas Samuel alone edits the videos.

The channel is best known for the pair’s viral dark MIDI piano piece “Rush E,” which gained popularity from a chain of comments on a fan’s cover of the song.
