Lauded by many fans as not only the best track on "Music," but one of the best songs in Madonna's entire career, "Impressive Instant" served as the unofficial theme song to her 2001 Drowned World Tour. Unfortunately, "Impressive Instant" was never released as a single, perhaps the biggest travesty in Madonna's career. Fortunately, a few remixes were commissioned and the track was serviced to clubs -- the perfect atmosphere for this trippy techno-infused opus to instantaneous attraction.

The song itself is without a doubt one of the most innovative of Madonna's career. Madonna's voice is filtered through auto-tuners and other special effects throughout the song, and producer Mirwais added unexpected vocal tics and twitches, pitch-shifting Madonna's voice when you'd least expect it. And then, of course, there's that bridge. "I like to singy singy singy / like a bird on a wingy wingy / I like to rhumba rhumba rhumba / dance to samba samba samba." When the lyrics were released before the song was available, fans scratched their heads at the incredibly bizarre lines -- but now this brief sing-along stands as a highlight on "Impressive Instant."

NOTE: The "single cover" used above is not real - it is a fan creation done by former Dotmusic and Madonnarama regular "InfidelRokkit."

TRIVIA: When William Orbit first heard "Impressive Instant," he was so awed by the Mirwais-produced track that he thought it easily outdid his own work with Madonna.
