On Monday's Good Morning America, singer-songwriter Sheryl Crow debuted her new song dedicated to Sandy Hook victims. Thursday this week marks the five-year anniversary of the tragic mass shooting in Newtown, Connecticut, which killed 20 students and six staffers.

Later that day, Sheryl unveiled her new music video for "The Dreaming Kind."

Her 12-year-old niece, Ava Crow, performed alongside her on Good Morning America, and is featured on the new song.

The tragedy, and all the ones that have followed, "weighed heavily" on her heart.

"The tragedy in Newtown 5 years ago and the countless lives lost in mass shootings since have weighed heavily on my heart," Crow wrote regarding the song, via Rolling Stone.

I felt compelled to write 'The Dreaming Kind' for the incredible people at Sandy Hook Promise who work so hard every day to combat gun violence. The extraordinary work this organization does to educate and protect our nation from further bloodshed gives me hope for a better tomorrow. I hope this song will inspire the same feeling in those who hear it.

The Sandy Hook Promise.

The nine-time Grammy winner is working in conjunction with Sandy Hook Promise, a nonprofit group co-founded by Mark Barden, whose son Daniel was killed in the Sandy Hook Tragedy. “The work of Sandy Hook Promise focuses on preventing gun violence before it starts,” he said in a statement.

A life-changing moment... then nothing happened.

Speaking to People, Crow talked about the "complete and total devastation and disillusionment" that comes in the aftermath of these mass shootings and how the Sandy Hook Promise hopes to prevent future tragedies.

"When Sandy Hook happened, we knew it was a life-changing moment where we were going to address the idea that not everyone should be approved to own a gun, especially military-style weaponry and yet, nothing happened," Crow said. "At some point, the alarm clock has to go off and we have to wake up."

Missouri State Representative Stacey Newman is all for waking people up, especially Republican lawmakers.

Sheryl made the song available for download, with all the proceeds going to the Sandy Hook Promise.

People love the song, calling it "beautiful."

Some people feel the real conversation about solving gun violence in our country has yet to be discussed.

That is a lot of guns -- nearly one each for 326 million Americans.

The trolls were at the ready to disseminate alternative facts.

And it seems some people can't help but be a critic
