Hurts So Bad': Exclusive Song Premiere

One of Jenni Rivera's last projects wasn't a solo. It was a duet with Edward James Olmos. They recorded the pop ballad "Hurts So Bad" for their film "Filly Brown," which is scheduled for release on April 19.

The track is premiering exclusively on Billboard (listen below). The song was written by Olmos, Rivera, Arthur Dominguez, Mico Olmos, Chris Perez, Edward "E-Dub" Rios and David Salas, who performs background vocals.

"That session was like Chicano heaven," says Lisa "Khool Aid" Rios, one of the producers of the film. "We feel honored to have been part of history that will live on forever."

Produced independently by Silent Giant Entertainment, which was founded by husband and wife team Lisa and Edward Rios, the film was shown at the Sundance Film Festival in 2012. The soundtrack goes on sale April 16.

The California-born Rivera, who died in a plane crash on Dec. 9 while working in Mexico, was on the cusp of a career breakthrough, going from a leading singer in the regional Mexican genre to recording music in English and venturing into other projects such as a sitcom loosely based on her life.

"Filly Brown," which was co-directed by Youssef Delara and Michael D. Olmos, features Gina Rodriguez in the leading role as Majo, an aspiring Latina rapper in Los Angeles whose mother (played by Rivera) is in prison and struggling with drug-addiction. Rodriguez learned to rap for the role and Rivera's performance, too, is receiving strong reviews worthy of awards.

"Hurts So Bad" was made in the tradition of an "oldies" song. The film also features other recording artists: Chingo Bling, Baby Bash, Dominator, Braxton Millz, MC Magic, Chrissie Fit, Ese Daz, Nikki Diaz, DamonReel, Jae Black, Fade Dogg, Carolyn Rodriguez, Malik and a spoken dedication to Rivera by Khool Aid:

"Dear Jenni -- You've left us with an empty place in our heart. It's not just an ordinary empty place. It's an empty place that needs to be filled in all we do moving forward... know that you'll live on."
