Reception

"I think the song is something that people aren't going to expect. It was inspired by a lot of the English rave and techno bands, but at the same time, it's pretty heavy. It's talking about insomnia, but it's really a tongue in cheek song about my life during the '80s, something that anyone who has ever been into staying up all night partying can relate to." (Mustaine, 1999)

"I took a psychology class recently while I was in Nashville, and I was surprised to find out that insomnia is not that you can't fall asleep; it is that you can't stay asleep. This reminded me of my many years of using stimulants and how hard it was to stay asleep, the sounds that you hear that may or may not really be there, and how my eyes felt. I felt like I was running on empty most of the time and a lot of the references in this song are actually true." (Mustaine, 1999)

"Those weird notes at the beginning were actually the last notes that I recorded for this album, and actually the last notes I recorded for Megadeth. This tune was kind of an afterthought and was almost completely Mustaine's. I was very impressed by the modern sounding stuff that he and Dann Huff came up with." (Friedman, 2002)
