Last Tuesday, Salvador started work on the song's music video, which was teased recently by Ivory on its official YouTube page.
"Believe", which has eight tracks, was earlier described by Salvador as being inspired by the music of pop stars Jennifer Lopez and Beyonce.
Noting the album won't feature "birit" or songs with soaring notes, Salvador shared that the tracks were tailor-made for her voice.
"Kung ano 'yung kayang ibigay ng boses ko, swinak nila. Kung ano 'yung babagay sa boses ko, iyon 'yung mga kantang binigay nila sa akin."
