Prince was diverse and talented enough to realize when he was writing a song that wasn't a Prince song. Such was the case, at the time, with "Kiss" which, believe it or not, was composed as a folksy/country song. Unable to finish it, he brought the demo track to his pet project du jour, Mazarati.
Who were obviously waiting for that perfect country/folk track to make it big time.
Unimpressed and kinda pissed, the band spent an entire day in the Paisley Park studio with engineer David Z completely rebuilding the track from the ground up. They retired for the night not believing the track was good enough. Or so they thought.
David Z returned the next morning to find Prince in the studio, tightening up his own freshly-recorded guitar and vocal tracks to the song. Reacting to Z's stunned confusion, Prince retorted that "This song is too good for you guys. I'm taking it back." This decision is likely the reason you had probably never heard of Mazarati before today.
Prince started cutting. He dropped the bass guitar off the track, along with all instruments but voice, guitar, drum machine and backing vocals. The result was shockingly sparse; only nine tracks were included in the mix down (most modern pop songs include roughly that many tracks for the vocals alone).
Prince is crazy!
When the people at Warner heard it, they kind of wondered where, you know, all the instruments and stuff were (they said it sounded like a demo). So if you're keeping score, the song was rejected by Prince, rejected by a shitty almost-Prince funk band and then reimagined as a sparse, bass-less song which was then almost rejected by the label.
Prince, probably after crossing his arms and whimpering in falsetto, told them that was the track they were getting and they better just deal with it. After a massive fight, the label reluctantly released it.
"Kiss" hit #1, and proved a triumph for a musician who was given more artistic freedom than pretty much any since. As for Mazarati, well, Prince later provided them with an outtake song by The Time called "Jerk Out" that made it nowhere until The Time took it back and made another # 1 hit off of it.
