DESC: Compilation producers: Leslie Lewis, Rob Senn. To get a sense of how the music industry at large perceives the urban-specific genres of hip-hop and R&B, one need look no further than the annual Grammy nominee collections that cherry-pick the highest-profile artists in those styles. The 2001 Grammy compilation is no exception, representing as it does the cream of the rap/R&B crop. Here are slinky R&B chanteuses (Toni Braxton, Erykah Badu), quirky upstarts (Sisqo, the notorious Eminem), mack daddy love men (Brian McKnight, D'Angelo), and straight-up hip-hop movers and shakers (Common, Mystikal, and the ubiquitous Nelly). One thing you can count on with each of these artists, given their Grammy standing, is the presence of undeniably catchy pop hooks, be they chants, riffs, choruses, or some amalgamation thereof. When 2001's music becomes oldies radio fodder, these are the songs you'll be hearing.
