Madonna co-wrote almost all of her songs from about her third album on, and co-wrote several on her first two. Many of her collaborators say she also provided a lot of lot of melodies and bridges on her songs, also, but yah, try to discredit her obvious talent and hard work. She is always involved from the beginning to every step of the recording of all her music. So yah, she's as involved in the songwriting process as Lennon-McCartney, Elton John-Bernie Taupin, Björn-Benny from ABBA, but sure, she just 'stole' other artists ideas... have a seat.
