From Princevault.com: “I Guess It’s All Over” is the eighth and final song on Mazarati’s first album MAZARATI, and, around the time of the album’s release, the track was included as the b-side of “Players' Ball”, the album’s first single. The track was written by Brown Mark as “We Did Things Our Way” before Prince re-wrote the lyrics and renamed the song “I Guess It’s All Over.” It was believed Prince was not involved in the track musically, but in 2017 Aaron Paul “Ace” Keith revealed that he played the guitar solo on the song.

While specific recording dates are not known, basic tracking took place in May 1985 at Sunset Sound in Hollywood, California, while Prince was working simultaneously in another studio in the building on the Parade album.
