“BEST INTEREST” is a loosie, unfinished song recorded during the IGOR recording sessions and released 6 months after the May 2019 album. The song and its accompanying music video were announced by Tyler on Instagram, as well as the second surprise release, “GROUP B.”

The song’s themes coincide with those addressed throughout IGOR, as Tyler expresses his frustration with a relationship where his significant other does not consider him as its main lover.
