1. ‘Purple Rain’ by Prince
Now that our patron saint of frilly-bloused, pan-erotic, disco-rock-sex-funk has sadly shuffled off this mortal coil, his signature slow jam can serve as much as tribute as a “let's-slow-things-down” showpiece in your karaoke rep. If it's not too lofty to put that pressure on what is—let's face it—a mostly frivolous activity, a karaoke run at ‘Purple Rain’ might even lift some spirits. Sung in a gracious middle key (Eb, as the preview screen helpfully reminds you) rather than Prince's frequent falsetto squeal, it should allow you to bare your soul without any embarrassing high-register mishaps.
