Prince was hardly on the radio when this came out, but this song was a big hit on the street and at dance parties. The bass line was just so funky.

This took everything to the next level. It sounded so funky and mysterious and scary. It was a monumental track for me.

I love the minimalist quality of this. There's a drum machine going with an overdub of live drums, and real simple synths. It's so funky.

It's a beautiful feeling that this song gives me. Wendy and Lisa on it – it was such a strong period when they worked together.

There's funky bass, slamming drums, and the melody is just incredible. This was his sound. He owned the big drum machine. Nobody else could do it.
