"Wag Na Lang" by the Filipino pop rock band Cup of Joe highlights the group's "experimental" approach to music, which integrates elements from acoustic pop, retro, alternative pop, retro-wave, and neo-folk. Formed in Baguio City, Philippines, in November 2018, the band's musical output is deeply influenced by their local environment, with songs often drawing inspiration from the city's scenic surroundings and cool breeze. This connection to their roots is evident in their sound, which has been described as featuring emotional lyricism, rich melodies, and youthful sincerity. The band's name itself, "Cup of Joe," was chosen spontaneously to reflect their relaxed musical style and their bond with Baguio. Cup of Joe, comprising lead vocalists Edgar Gian Bernardino and Raphaell "Rapha" Ridao, keyboardist Vixen "Xen" Gareza, lead guitarist Antonio Gabriel "Gab" Fernandez, and rhythm guitarist Clint Joules "CJ" Fernandez, signed with Viva Records in 2019.
