"There ain't no gold in this river/ That I've been washing my hands in forever/ And there is hope in these waters/ But I can't bring myself to swim when I am drowning in this silence/ Baby, let me in," Adele can be heard singing in the clip.
Thousands of followers tuned in to listen, including some familiar names such as Alicia Keys, who commented "snippet vibes" and Ben Platt, who summed up how we were all feeling with "IT'S HAPPENING".
The artist also answered a flurry of questions about the new track and her next album, which fans believe is titled 30 based on billboards that have recently popped up in locations all over the world.
Adele didn't want to "give too much away" about the upcoming album just yet.
"I do have a favorite song from the new album," she teased. "But I'm not gonna tell you what it is 'cause you don't have the track list yet."
"I'm excited to get it out into the world at last," she added.
She shared that the album is "dropping soon. Don't you worry".
Although she's previously said the new album isn't primarily a "divorce record", during the Instagram Live she told fans it was based on "divorce, babe. Divorce".
