Yesterday marked 10 years since Ol Dirty Bastard passed away. In memorandum we cued up a couple of his classic tracks, a playlist that included his remix to Mariah Carey’s chart-topping 1995 hit “Fantasy.” It as an unimaginable combo at the time, but it worked. His crazy style cascaded perfectly with her bubbly voice and dominated radio stations across the country when it was released. It was a shining example of the good that can come when the right rapper hops on an R&B song. There’s been a lot of talk lately R&B, especially stateside. Is R&B dead? What’s classified as alternative R&B? We’re not going to tackle those questions. Instead, we’re going to take a look at a certain type of song. Good R&B songs featuring rappers are rare these days, so we chose to chronicle the best of the best—everything from Joe and Mystikal to Jodeci and Wu-Tang. Songs where the rappers work hard not to just steal some shine, but to also improve the track already laid down by the singer. To be clear, we're not talking about songs where the singer also raps. We're talking about R&B songs made by R&B artists with a guest rap verse. Cool? Cool. Now, go ahead and check out the 50 Best R&B Songs With Rap Features.
