Elements of retro R&B and jazz give MAMAMOO's romantic cuts a timeless feel. They work in jazzy piano melodies and horn accents on sweet numbers such as “Mr. Ambiguous” and go full-on lounge on the keyboard-centric ballad “I Miss You,” adding a splash of rap for a contemporary vibe. This list highlights the outfit's sweetest moments and shows how throwback sounds can still make a love song bloom.
