DIPLO: Madonna has posted multiple photos of with the writer/producer/DJ in a recording studio over an an extended period of time, and he's gone on record as having written a number of songs with the Queen of Pop. Three of them, at least, are "amazing, smashes," he told Billboard for his recent cover feature.
Additionally, in an interview with BBC Radio 1, he said that they were "wrapping up the first single last week in New York," and that they are "fine tuning" the mix. So, it would seem that Diplo has emerged as the album's central producer, with Madonna. "I'm excited about that project," he told Radio 1. "It's one of the first ones I've done a majority of a lot of the production."
