Bump n' Grind (R. Kelly song)

"Bump n' Grind" is a song written, produced, and performed by American singer-songwriter R. Kelly. It was released on January 28, 1994 by Jive Records, as the second single from his debut solo studio album, 12 Play (1993). The track became a number one single on the US Billboard Hot 100 (temporarily interrupting the six-week run of Ace of Base's "The Sign"), and it also spent twelve weeks at number one on the US Hot R&B Songs chart as Kelly's third number-one R&B hit, becoming the longest-running number-one of 1994 in the US, and the longest-running R&B single at that time. The song also reached number eight on the UK Singles Chart, following the massive success of his previous single, "She's Got That Vibe" (which was actually a re-release).
