Singer-songwriter Gary Granada who is the artist behind songs like “Mabuti Pa Sila,” “Pag Nananalo ang Ginebra,” and “Yan ang Aming Barangay,” is crying foul over GMA Kapuso Foundation’s allegedly taking advantage of his work.

In a 14-minute audio file sent via e-mail to friends, colleagues, the media, and now has been making the rounds via blogs, Plurk, and Twitter, Granada said GMA Kapuso Foundation commissioned his services for their “Tripid Handog Edukasyon” jingle’s music. He said the study tape he submitted was disapproved, but that the final product, which aired in December, bears a striking resemblance to the one he submitted.

Meanwhile, GMA-7 said it already had contacted the composer of the approved ad jingle, which Gary Granada claims to have used the basic structure of his own work and that they are still waiting for the response.
