MGMT have shared the third single from Loss of Life, their first album since 2018’s Little Dark Age, due out February 23 via Mom + Pop. “Nothing to Declare” — not to be confused with 700 Bliss’ 2022 album of the same name — is a forlorn acoustic guitar ballad that nevertheless fits snugly into a three-and-a-half-minute runtime, never lingering too long in its most emotional moments.
