Kacey Musgraves and Ty Herndon sing on the new charity single “Hands,” a musical tribute for those affected by the Orlando massacre on June 12. Proceeds will support victims and families through the Equality Florida Pulse Victims Fund, the GLBT Community Center of Central Florida and GLAAD.

Written by Julia Michaels and Justin Tranter, former front man of Semi Precious Weapons, the song features Mary J. Blige, Jason Derulo, Tyler Glenn, Selena Gomez, Halsey, Imagine Dragons, Juanes, Adam Lambert, Mary Lambert, Jennifer Lopez, the Trans Chorus of Los Angeles, MNEK, Alex Newell, P!nk, Prince Royce, Nate Ruess, RuPaul, Troye Sivan, Jussie Smollett, Britney Spears, Gwen Stefani and Meghan Trainor.

“The second I heard about this horrible tragedy where so many of my LGBTQ brothers and sisters lost their lives, I immediately got on a plane to Orlando to volunteer my help anyway I could,” Tranter said. “Putting this charity single together is just a way for me, and everyone involved to keep volunteering our help and promote peace and love in the world."

Tranter and Michaels are behind No. 1 hits for Selena Gomez (“Good For You”) and Justin Bieber (“Sorry”). They also co-wrote Gwen Stefani’s “Used to Love You.”

Herndon hosts the GLAAD-sponsored Concert for Love and Acceptance during Nashville’s annual CMA Music Festival. In 2014, Musgraves became the first country star to perform at the GLAAD Media Awards for its 25th annual event.
