"Into the Groove" consists of instrumentation from synthesizers and drum machines. Madonna's voice is double tracked in the chorus; the song also consists of musical contrasts, overdubs and Madonna's voice in lower register during the bridge. The lyrics of the song are simple, written as an invitation to dance with the singer. However, it carries sexual innuendos and undertones in the meaning. The song received positive reviews from music critics and was a commercial success. "Into the Groove" topped the record charts in Australia, Belgium, Ireland, Japan, Netherlands, New Zealand, Spain, and became her first number-one song in the United Kingdom. The song was only available as the B-side of the 12-inch single of "Angel" in the United States, therefore it was ineligible to chart on the "Billboard" Hot 100 at the time. "Into the Groove" has appeared on three Madonna compilations: in a remixed form on "You Can Dance" (1987), "The Immaculate Collection" (1990), and in its original form on "Celebration" (2009).
