The lead melody was inspired by the synth line in Stevie Wonder's "Superstition".

While "Ghosts 'n' Stuff" (featuring Rob Swire) became the radio-friendly anthem, "Moar Ghosts 'n' Stuff" serves a different role in deadmau5's discography:

On For Lack of a Better Name , "Moar Ghosts 'n' Stuff" actually precedes the vocal version , acting as an extended, atmospheric build-up.

The track is heavily themed for Halloween and features a vocal sample from the 1957 sci-fi film The Brain from Planet Arous and a quote from Chopin's "Funeral March".

It is frequently cited as a pioneer of the "complextro" movement due to its call-and-response synth patterns.

Unlike the main single, which features the vocals of Rob Swire , "Moar" is primarily instrumental, focusing on a more aggressive, groove-heavy bassline.

The track's roots trace back to 2004, with early demos titled "Old Ghosts" and "Old Hotels". Zimmerman eventually finalized the track for a performance on Pete Tong's BBC Radio 1 show in October 2008, where he renamed it after Tong suggested his hotel was haunted.
