Kahan "calls...back" Musgraves

Adding a new verse and perspective to the song, Musgraves sings a conversational back-and-forth with the breakout Vermont singer and songwriter over a buoyant guitar riff and beat.

She sings, "You love me, and I don't know why. I only call you once a week," as he counters on the hook, "Everything's alright when she calls me back."

Kahan said, "Kacey Musgraves is the coolest person ever. Not exaggerating when I say that during the 'Stick Season' album process, we would finish a song, and I'd listen back and be like 'Can you imagine Kacey on this?' Having her sing on 'She Calls Me Back' is incredible, and being able to have her continue telling the story adds a whole new dimension to the song and what it means. I'm so grateful and honored, continually humbled that artists of this level have lent their voice to this album. Kacey is cool as hell, brilliantly talented and represents everything I love about music. She is a true artist, and I can't thank her enough for being a part of this song."
