American singer Madonna has released 83 singles (including 1 as a featured artist) and 12 promotional singles. In 1982, she signed a contract with Sire Records and Warner Bros. Records, and released her first two singles before launching her eponymous debut album. Her first entry on the US Billboard Hot 100 was “Holiday” (1983), which peaked at number 16. The following year, Madonna released “Like a Virgin”, which reached number one in Australia, Canada and the US; the latter it spent six weeks atop the chart. The album Like a Virgin spawned three other top five singles: “Material Girl”, “Angel”, and “Dress You Up”. In 1985, Madonna released her second US number-one single, “Crazy for You”, and her first UK number-one single, “Into the Groove”, both from motion picture soundtracks.
