You don't produce Madonna, you collaborate with her. She's a really good producer herself and obviously a great writer too. I've never worked with anyone before who is as genuine and as hands on as an artist as Madonna is. She's has her vision and knows how to get it. What's interesting with this one is that she's picked a DJ to make dance tunes for her to make songs, which is exactly what she's been doing since 1983 - hanging out with DJ's and making records.
