Pop music has always traded in the currency of longing. From Dusty Springfield’s orchestral heartache to Lana Del Rey’s slow-motion melancholy, the genre’s most enduring moments are invariably those that refuse to resolve — that hover, suspended, between the ending and the aftermath. Sabina Chantouria understands this instinctively. On *Can’t Let You Go*, her latest single, the Swedish-Georgian singer-songwriter doesn’t merely revisit familiar emotional territory; she excavates it, turning over the soil until she finds something luminous and uncomfortably true buried beneath.
