On which record label did the singer Madonna's first hits appear?

Madonna Louise Ciccone (born August 16, 1958) is an American singer, songwriter, and actress. Having been referred to as the "Queen of Pop" since the 1980s, Madonna is noted for her continual reinvention and versatility in music production, songwriting, and visual presentation. She has pushed the boundaries of artistic expression in popular culture, while remaining completely in charge of every aspect of her career.

Madonna with her then boyfriend Stephen Bray formed the band Emmy. The two began writing songs together, but Madonna later decided to promote herself as a solo act. Her music impressed DJ and record producer Mark Kamins who arranged a meeting between Madonna and Sire Records founder Seymour Stein. After Madonna signed a singles deal with Sire, her debut single, "Everybody", was released in October 1982, and the second, "Burning Up", in March 1983. Both became big club hits in the United States, reaching number three on Hot Dance Club Songs chart compiled by Billboard magazine.
