I am a huge Prince fan, and I have been for a very long time. There's not much that this man has done that isn't brilliant on some level.
This single, one of my favorites - and a song that I can sing word for word unprompted - was one that Prince, a perfectionist, worked on for almost four years, before he released it as a single. And, for a song first recorded in 1982 and released in 1985, it still sounds fresh and new and unique. This is a testament to the musical genius of Prince - he is multi-instrumental, deals with themes in his lyrics that no one else does, has a tremendous grasp of how to properly use a metaphor, and surrounds himself with musicians that are as strong as he is.
To that last point, look at how prominently Wendy Melvoin, on guitar, is featured in this video. In fact, the entire Revolution - including a strings section - are featured at several points. To those who claim Prince to be an egomaniac, I point you to the 3:38 point in this video, when it is made clear that Lisa Coleman is the 2nd vocalist. This is a theme that recurs through several Prince videos. The man knows music, and he knows he can't do it alone.
