B2K will primarily be remembered as the jumping-off point for Omarion's career, but most people forget that the group did have a series of hits during their peak. And of those singles, they all bowed down to the greatness of "Bump, Bump, Bump," which ascended to the top spot on the Billboard Hot 100 on this day in 2003.
The group — consisting of Omarion, Lil Fizz, Raz-B and J-Boog — first began to make noise in late 2001 with the single "Uh Huh." B2K's sound wasn't straight pop (they borrowed a lot from hip-hop-influenced R&B groups of the late '90s like Jagged Edge and 112), but they were presented as the urban alternative to the glut of boy bands (who were still in steady command of the pop charts even after the turn of the century). Their self-titled debut hit in early 2002 and scored the group two more singles, but their big breakthrough came following the release of their second album Pandemonium! in late 2002 (just after the release of the group's Christmas album Santa Hooked Me Up, perhaps the most awesomely-titled holiday collection of all time).
With an assist from Diddy, "Bump, Bump, Bump" climbed up the Billboard Hot 100 until it finally reached the top, finally ending the reign of Eminem's "Lose Yourself" (which was on top for a staggering 12 straight weeks). Unfortunately, the stay at the top for "Bump, Bump, Bump" was only temporary, as it stepped aside in favor of Jennifer Lopez's "All I Have" after only one week (the Lopez song, featuring a guest verse by LL Cool J, was in the number one position for four weeks before ceding it to 50 Cent's "In Da Club"). For a brief moment, B2K were on top of the world (though they broke up shortly after), and they have the video for "Bump, Bump, Bump" to remember their time in the sun.
