“Doesn’t Really Matter” from Nutty Professor II is Janet Jackson’s ode to the “inner being,” that it “doesn’t really matter what the eye is seeing.” Its message a fitting one for the film, as Jackson’s character, a professor, plays the love interest of the reserved Professor Sherman Klump (Eddie Murphy), who has a Jeckyll & Hyde struggle with his larger physical stature. The song has undergone various incarnations (a music-video version; album/tour version), yet Jackson’s familiar breathy vocals over the fast-paced, syncopated lyrics remain. The All For You album track has an “edit” before the second chorus, and later a “rock mix”, both serving as opportunities for Jackson’s signature “dance breakdowns” during performances.
