Crazy Town were an American rap-rock band who caught the nu-metal wave at its commercial peak, and they rode it to a surprise number-one hit. "Butterfly", released in 1999 and a chart-topper in 2001, was softer and catchier than their harder material, built on a guitar sample from the Red Hot Chili Peppers' "Pretty Little Ditty".
The success was sudden and did not last. Fronted by Seth "Shifty Shellshock" Binzer, the band's heavier songs never found the same audience, and internal turmoil cut their moment short, leaving "Butterfly", a song that sounded little like the rest of their work, as the one track most people remember.
On streaming, it sits near 666 million plays, while their next most-streamed song trails at around 12 million. That sends the ratio above 56, many times our 5.0 line.
By our measure Crazy Town are a certified one-hit wonder. Their story is a familiar one for the era: a band whose biggest song was also their least typical, a borrowed-sample ballad that briefly conquered the charts and then stood alone. It is the nu-metal era distilled: maximum exposure, then very little staying power.
