MANILA, Philippines – Singer-songwriter Rico Blanco has blasted Lakas-Kampi-CMD standard bearer Gilbert “Gibo” Teodoro for using his composition, Rivermaya’s “Posible,” in one of his political advertisements, claiming that it was done without permission.

In his Twitter account, a pissed Blanco wondered how a presidential candidate like Teodoro “can overlook a simple matter such as intellectual property.”

“i'd like to understand how can a presidentiable can overlook a simple matter such as intellectual property. command responsibility,” Blanco, Rivermaya’s former vocalist, tweeted. “even HS students ask permission from me if they want to use my songs for their school projects… and they dont even have to.”

Blanco was surprised that the singer in the political ad even copied his voice. He said this might give an impression that he is supporting Teodoro in the coming elections.

“ok finally saw it. very nice ad. but wow. they even copied my singing/voice. so it cant be that they just werent aware i existed. sakitsaulo,” he said.

He acknowledged that Teodoro is a smart person, “but if you can't run a good campaign how can you run a country?”

The singer also argued that notifying the song composers is a sign of respect. “when we did the tribute album i made it a pt 2 get composers nod even when publishers assured us they had rights. iba yun eh. RESPETO lang.”

“ATTENTION PEOPLE IF YOU WANT TO USE ANY OF MY COMPOSITIONS TALK TO ME DIRECTLY. i will point you to the proper publishers if any,” he said.

It was reported that Tedoro’s camp paid the record label, Viva Records, for the rights.

Despite this “very strange intellectual property issue,” the singer is giving the administration’s presidential candidate the benefit of the doubt. He said his camp is already talking to Tedoro’s team, adding that he hopes the issue will be settled soon.

“To be fair, he is on my very short list. so i hope things get sorted out. he seems to be smart and all,” said Blanco, who appeared in the music video of ABS-CBN's election campaign, “Boto Mo, iPatrol Mo (BMPM): Ako ang Simula.”

Blanco’s tweets have been a subject of discussions in various blogs as well as on Facebook and Twitter, with some asking if the issue could affect Teodoro’s chance in May polls.
