She's been recording for 20 years. Here are the pop diva's five essential albums:
(1983). A dance-floor classic from start ("Lucky Star") to finish ("Everybody").
•Like a Virgin
(1984). Sassy, sexy synth-pop defining the Material Girl.
•Like a Prayer
(1989). An inspired Madonna
expresses herself better than ever before vocally and lyrically.
•The Immaculate Collection
(1990). This CD of all the '80s hits shows her uncanny knack for great singles.
•Ray of Light (1998). Electronica gives Madonna
a creative charge.
