"Let's Go," the latest single from Madi Diaz, is an indie-folk gem about the difficulties of moving on. "It really wrote itself," the Nashville singer-songwriter tells Rolling Stone. "After messing around with the track and listening and experimenting for a little, it just sort of fell out. The melody felt like it had been wafting around in the room and all we had to do was reach up and catch it." Diaz insists that the song is lighter than her previous material, but while the mid-tempo track feels uplifting, there's something chilling in the way she "oh"s.
