The track "Cut Chemist Suite" from Southern California Latin hip-hop/rock band Ozomatli's self-titled 1998 album is available for free download in the controversial MP3 format at RioPort.com. Also available for free download on the site is a song from pop-rock band Gus, "Laugh I Could Learn to Love." A spokesperson for the site said the promotion is the first of many such events with acclaimed artists. Both songs will be available for a minimum of two weeks, starting Friday (Apr. 16). Also, a Rio portable MP3 player will be given away each day during the promotion to one person who downloads the Gus song and one person who downloads the Ozomatli song.
