"Best Friend" is an dance song with urban and R&B influences by American singer Brandy. It was written by Keith Crouch, and Glenn McKinney and produced by Krouch for her self-titled debut studio album, Brandy (1994). The song released as the album's third single in June 1995 (see 1995 in music). With peak positions of number 11 in New Zealand and number 34 on the U.S. BillboardHot 100 the song was moderately successful. However, "Best Friend" peaked at number 7 on the Hot R&B/Hip-Hop Songs chart. The song was also featured on her hit series Moesha where she and Kim (Countess Vaughn) cheerleading in the final scene of the episode "Friends" that aired in the same year. Hence the title of the song, the song was dedicated to her brother Ray J.
In his review for Billboard, Larry Flick wrote: "Brandy's cachet as one of the freshest young talents to emerge ín recent memory continues to increase. This third single from sterling eponymous collection follows the jeep-pop vibe of "I Wanna Be Down" and "Baby", while also going for a slightly harder-edged groove in rambunctious remixed by Troy Taylor and Charles Farrar. At alle times, Brandy's sweet and girlishly soulful delivery is center stage – as is the song's wickedly infectious hook. Another out-of-the-box smash.
