Fancy yourself as a bit of a singer but need some inspiration? The Inter American Press Association (IAPA) has launched a music contest to draw attention to and fight impunity involving crimes against journalists in the Americas. The "Lend Your Voice to the Voiceless" contest - wrapping up at the end of March - invites the public to participate by posting videos, songs or lyrics about crimes against journalists on their new website, Lend Your Voice, available in English, Spanish and Portuguese.

Fledgling artists from Brazil, Mexico, Colombia and the U.S. kick off the campaign with some promotional videos available on the site, including the catchy tune by Latin Black "No podemos callar" ("We cannot be silent"). Watch it here:

Not sure exactly what to sing about? IAPA makes it easy with an outline of some of the emblematic cases of journalists killed under the section "Find inspiration here".

For the musically challenged, use your voice by voting for your favourite video or signing IAPA's petition to end impunity - both available on the site.

IAPA say it will use Facebook, MySpace, Twitter and YouTube to encourage Internet users to join the anti-impunity cause. The winner will have their song professionally recorded.

While crimes against journalists have not decreased in the Americas - with at least 21 murders so far this year alone - in recent years there has been a notable increase in the prosecution and conviction of criminals, says IAPA.
