"Let It Go" is a song by R&B singer Keyshia Cole released as the lead single from her second album, Just Like You (2007). It features rappers Lil' Kim and Missy Elliott. Elliott also produced the song, which samples "Juicy Fruit" by Mtume, and "Don't Stop the Music" by Yarbrough and Peoples. This song also interpolates "Juicy" by The Notorious B.I.G., who also sampled "Juicy Fruit", and had a relationship with Lil' Kim. The single debuted on the Billboard Hot 100 at number 74 on the issue date of July 7, 2007, and peaked at number 7, becoming Cole's third top ten hit single altogether and first top ten Billboard Hot 100 single as a lead artist. Due to heavy requests, Z100 finally started rotating the track in late September 2007. It also became Cole's first number 1 hit on the R&B/Hip-Hop Songs chart. It was nominated in the 'Best Rap/Sung Collaboration' category at the 50th Annual Grammy Awards to be held February 2008. This song was number 59 on Rolling Stone's list of the 100 Best Songs of 2007. "Let It Go" has sold over one million copies in the U.S. and has been certified platinum by the RIAA.
"Let It Go" is about female empowerment and failed relationships. It is about "letting go" of a relationship if one partner is not there for the other, and is not interested in showing love or respect. The song "Let It Go" was originally intended for Fantasia for her self-titled album, but she had too many songs on that album, and Cole wanted it after Elliott played it for her. According to 50 Cent in a Hot 97 interview the song was also offered to G-Unit artist Oliva who picked another Missy Elliott track instead. Lil' Kim appears on the record to pay homage to Biggie, as the song is similar to his hit "Juicy".
