Regulo Caro will present his new disc "En Estos Dias" (In These Days), which includes the hit number "Cicatrices" (Scars), on Oct. 7. The Mexican singer has highlighted his songwriting skills in his fifth studio album.

"It's a very personal song and something I have been through — the experience of having a loved one in jail," Caro said of "Cicatrices" while speaking to EFE, a Spanish international news agency, in a telephone interview. "It's a situation that deeply affects both family and friends. And this very emotional, sad and melancholy subject is something a lot of people can identify with."

Caro said the response to the lyrics of the songs has been great. Some of the songs from the studio disc has already aired on leading radio stations in the U.S, according to Fox News Latino.

The 34-year-old, who is mostly known as a singer of corridos, has also recorded songs with controversial lyrics about the world of drug-trafficking. 

"In all my discs I've always tried to include numbers of this kind (with social content), but they haven't been promoted," he said. "Sometimes thoughtful songs like that go unnoticed by the public, unlike corridos...because people always want to hear happy tunes. I've written other lyrics like this, but they've never been picked for singles."

Caro, who was born in Los Angeles but raised in the Mexican town of Obregon, is celebrating the sixth year of his musical career. He has been nominated for a Latin Grammy, a BMI Pop Award, a Golden Disk and a place on the Walk of Stars in Las Vegas during his career.

He debuted "Cicatrices" in February, attracting over 43 million views on YouTube. In August, he released the second single, "En Estos Dias," which has more than 7 million views as of Tuesday.
