Four of the songs on Hormoaning are covers which had not been released previously. The remaining two songs are Nirvana originals which previously appeared as b-sides to singles for Nevermind.
"Aneurysm" and "Even in His Youth", two Nirvana originals produced and engineered by Craig Montgomery, also appear as b-sides on the "Smells Like Teen Spirit" single. This version of "Aneurysm" later appeared on disc two of the rarities box set With the Lights Out in 2004 and is different from the version released on Incesticide in 1992.
