Halsey, Gwen Stefani, Kacey Musgraves, and more team to raise money for Pulse Nightclub victims

Jennifer Lopez, Meghan Trainor, Juanes, Pink, Mary J. Blige, and Britney Spears have also taken part in the song, which is being released to raise money for the victims of the 12 June attack.

Justin Tranter (who's written for Justin Bieber, Fall Out Boy, and more) has spearheaded the song with support from GLAAD and Interscope.

Ty Herndon, Dan Reynolds of Imagine Dragons, Adam Lambert, The Trans Chorus of Los Angeles, MNEK, Alex Newell, Mary Lambert, Prince Royce, Mark Ronson, Jussie Smollett, Nate Ruess, and RuPaul have all also added their talent to the final version of "Hands".

"We assigned everybody what we thought would be the best part for their voice," Tranter says to Billboard, "and we asked them all to sing an additional part, just in case. But everybody got it done in time so we ended up with extra vocals. [In Los Angeles] Interscope let us use their studio... Mary J. Blige recorded in New Orleans. Britney Spears in Thousand Oaks, I think. Pink in Santa Barbara. MNEK recorded at home in London. Selena recorded in her studio bus. Dan Reynolds recorded in his home. Adam Lambert was in Luxembourg. Ty Herndon the country star was in Spain. Kacey Musgraves, Nashville. Everyone just got it done."

"We didn't want to have any trendy electronic elements," Tranter adds. "We wanted it to sound classic, timeless and human. We want this anthem of positivity to be played for years to come."
