Answer:
Original Pilipino Music, now more commonly known as Original Pinoy Music, Original Philippine Music or OPM for short, originally referred to Philippine pop songs, particularly ballads, that were popular in the Philippines during the late 70s to the present. OPM artists such as Rico Puno Jr., Ryan Cayabyab, and Celeste Legaspi in the 70’s, and Regine Velasquez, Sharon Cuneta, Martin Nievera, Pops Fernandes, among many others led the way in the 80’s and 90s.
Today, OPM is experiencing a bit of a resurgence, with new Pilipino underground artists like Jess Connelly, BP Velazquez, CRWN, Lustbass (from Manila Rising event last year curated by Mark Herlihy) and more creating a new OPM sound. Oakland party crew ASTIG OPM has a monthly night dedicated to the past, present, and future of OPM music. Record collectors are even digging for Pilipino rare grooves on vinyl.
Organum, plural Organa, originally, any musical instrument (later in particular an organ); the term attained its lasting sense, however, during the Middle Ages in reference to a polyphonic (many-voiced) setting, in certain specific styles, of Gregorian chant.
