The B-side was the cult fan favorite "17 Days", which was originally intended for Apollonia 6's self-titled album. A 12-inch single issued in the UK included "17 Days" and two tracks from Prince's previous album, "1999:" its title track and "D.M.S.R.". The entire title of "17 Days (the rain will come down, then U will have 2 choose, if U believe, look 2 the dawn and U shall never lose)" is now the longest-titled flip side of a Hot 100 No. 1, with 85 letters and/or numbers.
