I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "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. After this success, she started developing her debut album, Madonna, which was primarily produced by Reggie Lucas of Warner Bros. However, she was not happy with the completed tracks and disagreed with Lucas' production techniques, so decided to seek additional help."?
Whose work did Madonna not approve of?
