Madonna has a very unique style and comes up constantly with these great songs.

Let their music skill speak for [itself]. If they are producing good tracks and are resonating with their fans, or even gaining new fans, then that's great.

I had Ice Cube on my first album, "Bunker," and then I did a remix for Snoop Dogg. I've worked with Grandmaster Flash and Pharrell. It's a different work process and there's a different take with how you produce [hip-hop].
