Several out artists have responded to this weekend's attack on a gay nightclub in Orlando with new music.

Melissa Etheridge told Rolling Stone that she wrote Pulse while on tour.

“I'm dealing with it the way I deal, which is, I wrote a song,” Etheridge said. “I just sat here, and I just started writing a song... That's how I first started to cope because, as a singer songwriter, I feel very... I've done this before. I feel called to speak; to do what musicians do. We've been the town criers for hundreds of years. We're mirrors of society. We want to try to make sense. We want to try to heal. We want to bring some meaning, some purpose. We also want to put it down forever in history. That's how I'm coping.”

Forty-nine people died when a lone gunman opened fire early Sunday morning in Pulse nightclub. Several of the dozens injured remain in critical condition.

Etheridge appears to be speaking to the gunman when she sings: “Who you gonna hate now?; When there's no one left but you?; Who you gonna gun down?; If you can't kill the truth; That it's inside of us; Inside our blood; Inside our pulse.”

Etheridge, who premiered the song on Wednesday, said that all proceeds from the track will be donated to an LGBT charity.

Eli Lieb and Brandon Skeie also produced a powerful song titled Pulse and dedicated to Sunday's victims.

Lieb sings: “I'm in chains 'cause I'm choosing; Showing love or living life; I shouldn't have to leave where I stand; I shouldn't have to change who I am; To count as a human; Feel my pulse.”
