Songfacts®:

• Here, Russ links up with Massachusetts rapper BIA to rap about the bedroom chemistry both have with their lovers. This is Russ' first collaboration with Bia.
• BIA (born Bianca Landrau) broke out in 2016 when she released a pair of viral hits with "Whip It" and "Gucci Coming Home," and a couple of years later landed a writing credit on Camila Cabello's single "Sangria Wine."
  
  Here, she raps the second half of the chorus. Later on, BIA spits an explicit verse where she describes the great sex she has with her lover.
• Jahaan Sweet and Boi-1da's production adds to the song's raunchiness by incorporating bed squeaks.
• During his verse, Russ shouts out Rihanna's tattoos and her contribution to Jay-Z's 2009 hit, "Run This Town." The Barbadian beauty responded by giving "Best On Earth" a heads-up on her Instagram. Rihanna's co-sign gave the song a major boost in its climb up the Hot 100.
