"Metanoia" is the special limited edition single release that was originally a b-side on MGMT's debut CD single "Time to Pretend". It was released August 18, 2008, available in 10"etched vinyl.
"Metanoia" was named "Song of the Day" on September 16, 2008 by Rolling Stone, describing it as a "14-minute opus, which ranges from Donovan-ish acid ballads to interstellar synth-powered dirges to falsetto-laden theater rock."
Psychologist Carl Jung is the "mystic referee" referred to throughout the song. He is pictured wearing a referee's uniform on the title cover. Metanoia is also a psychoanalytic theory developed by Jung himself.
