Original Pilipino Music, now more commonly termed Original Pinoy Music, (frequently abbreviated to OPM) originally referred only to Filipino pop songs, especially those in the ballad form;    refer to songs popularized in the 1970s through the mid-1990s by major Filipino pop artists like Ryan Cayabyab, Sharon Cuneta, Kuh Ledesma, Zsa Zsa Padilla, Martin Nievera, Gary Valenciano, Basil Valdez, Rey Valera, Regine Velasquez, Ogie Alcasid, Jaya, Lani Misalucha, Lea Salonga, Janno Gibbs and the APO Hiking Society.  In the passage of time as well as the development of many diverse and alternative musical styles in the Philippines, the term OPM now loosely refers to any type of original Philippine Music created in the Philippines or composed by individuals of Philippine descent, regardless of domicile.  The lyrics may be in any language - usually either in Tagalog, English or taglish (a combination).

OPM emerged from an earlier genre called Manila Sound. It has eventually grown into a blanket term for Philippine popular music, including genres such as Pinoy Rock, Pinoy Jazz and Pinoy Alternative.
