Songfacts®:

• This is the first official single from Canadian progressive house producer Deadmau5's second album For Lack of a Better Name.
• Guest vocalist Rob Swire is the lead singer of Australian-British electronic rock outfit Pendulum, who are best known for their UK top 10 hit, "Propane Nightmares." The two had been bumping into each other backstage at various festivals and eventually agreed to this collaboration.
• The ghoulish dance track could be the start of a new genre: "Haunted House!"
• Deadmau5 (pronounced "dead mouse"); whose real name is Joel Thomas Zimmerman, explained his stage moniker to MTV News: "Long story short, a mouse went into my computer and died, and I found him in there when I was changing my video card," he said. "After word spread on the Internet through various chat rooms and blogs, "everyone just started calling me 'that dead mouse guy' because of he story, and it just stuck. And the 5 was because I couldn't spell out D-E-A-D-M-O-U-S-E because it was too long to have as a name in the chat room, so I had to trim a character, so I was just like, whatever, and I put a 5 in there and it stuck."
• The tune was used in the promo for America's Best Dance Crew season 5.
