Yeah! — Usher ft. Lil Jon & Ludacris (2004)

"Yeah!" stands as the crunk-R&B fusion that dominated 2004, achieving No. 1 on the Billboard Hot 100 for 12 consecutive weeks—nearly matching the 13-week streak of #1 "Umbrella." Its irresistible call-and-response hook between Usher and Lil Jon drives a production built on a minimalist synth riff, while Ludacris' rapid-fire verse adds raw energy. This song outperforms #6 "Beautiful Day" in commercial impact, with over 5 million digital sales, and remains the most inescapable club anthem of the decade. The track's longevity is proven by its position as one of only three songs from 2004 to rank among the top 50 best-selling digital singles of the 2000s, cementing its cultural footprint.
