28. Bad Meets Evil, "Scary Movies" (1999)
For some, Royce the 5'9" was still the best MC in Detroit in August of 1998, when he and Eminem paid a rite-of-passage studio visit to Stretch Armstrong and Bobbito Garcia's influential New York underground radio show. Em and Royce flung freestyle spittle for 12 relentless minutes, stoked by what bystander Noah Callahan-Bever called "a pharmacopeia of drugs." Just more than a year after that dazzling display and the transformative impact of The Slim Shady LP (which featured Royce on the track "Bad Meets Evil"), the duo released an indie 12-inch. The B-side, "Scary Movies," was the keeper, a peak indie-'99 banger, with a strings-swept, RZA-gritty thump and some of Em's most ferocious rhymes – "Any man plannin' to battle'll get snatched outta his clothes so fast it'll look like an invisible man standin'." But playing sidekick to Em didn't suit Royce and their paths eventually diverged until an eventual rapprochement (and reunion album) after the 2006 death of their mutual friend, D12's Proof.
