"Sofi Needs a Ladder" is the third single taken from deadmau5's album, 4×4=12. The song features vocals from Sofia Toufa as Sofi. The song was originally an instrumental track entitled "You Need a Ladder," which deadmau5 previously performed, but vocals were added on afterward to allow the song to be published and avoid any copyright infringement (the song previously included an intro and outro featuring a slightly remixed version of 'Overworld theme' from the NES game 'The Legend of Zelda'). The song was first played on the radio by Annie Mac on BBC Radio 1 on 22 October 2010. The song won a 2011 Juno Award for Best Dance Recording.
