Habang Buhay comes from Filipino singer songwriter Zack Tabudlo, who released the love song in 2021 and saw it become one of the defining OPM tracks of that period in the Philippines. Built as a devotion to a partner, it spread widely through streaming, radio and short video platforms, where fans kept recutting favourite sections. This RNB version reframes the familiar melody with a smoother groove, which is why it keeps resurfacing for romantic edits, dedications and fan made clips long after the original release period online.
