#5: Crazy Town — Butterfly (2001)
This rap-rock crossover loop dominated global youth culture for a few intense months before rapidly disappearing behind changing alternative musical eras. By lifting an intricate, fluid guitar progression from the Red Hot Chili Peppers and layering it under soft, hip-hop-inflected vocal deliveries, the band manufactured an inescapable radio staple. The track stands as the absolute peak of the millennium nu-metal pop crossover boom.
