14. Method Man feat. Mary J. Blige – "I'll Be There for You/You're All I Need to Get By"
"All I Need" is widely considered the first track to successfully conjoin R&B and hip-hop – two genres that hated each other with a passion before it was discovered they're like peanut butter and jelly. Sure, it took the queen of hip-hop R&B to tempt one of Wu-Tang's premiere weedmongers to do it, but the result changed pop history. Two New York street stars expressing their love to each other in the shadow of Marvin Gaye and Tammi Terrell, whose "You're All I Need To Get By" they sampled and interpolated. "You are my destiny," sang Blige, while Meth dropped lines about her beauty and strength — but not before shouting out "cheeba," setting another precedent: the rapper who shields his love for a woman with other, more day-to-day concerns.
