"Rough Untitled (idk)" is an unreleased song by Mars Argo that used to be available for streaming on her SoundCloud in 2013. The song is exactly what the title implies, a rough demo. It features Mars humming over a beat for a few minutes in the place of lyrics, and then the song repeats. The audio for this song was incorrectly leaked as a song titled "Dark Basement 1", and the title of "Rough Untitled" was given to the song "Doctor" when a live performance of it leaked online. It's currently unknown if lyrics were ever written for this song.
The song samples a bass riff from the rap song "I'm a Player" by Too $hort, which was originally sampled from "Hollywood Squares" by Bootsy's Rubber Band.
