This set highlights the diverse and talented nominees in the pop music categories for the 42nd annual Grammy Awards. Standing proudly at the helm of the early-21st-century boy-band craze, Backstreet Boys tell how they want it with sweet, soulful vocal harmonies in "I Want It That Way." Before the media seized upon what it dubbed a Latin pop explosion, heartthrob Ricky Martin was "Livin' la Vida Loca" and a breakaway second career. Arguably the most infectious song of 1999, "Smooth," delivered legend Carlos Santana to a new generation of fans, with the help of Matchbox 20's Rob Thomas. Supreme R&B divas TLC jam on the quintessential anthem for the modern, no-nonsense woman in "No Scrubs." Macy Gray's soul-drenched R&B shows how the slow groove was meant to be done on "Do Something." After years as an underground artist, Kid Rock broke through with the Metallica-meets-Run-DMC track "Bawitdaba." "I Need to Know," as the flagship track to his English crossover album, made Marc Anthony an overnight smash. And no compilation of the best pop tracks of 1999 would be complete without Lou Bega's "Mambo No. 5 (A Little Bit Of)," which dominated airwaves and dance floors unlike anything since "The Macarena."
