Palmy’s soulful ballad, "สนิทใจ" (Sanit Jai), acts as the main theme song for the 2023 drama Rak Rai . The lyrics explore themes of love, trust, and the painful realization of betrayal through a melancholic, piano-driven melody. The track emphasizes the vulnerability of giving one's heart entirely, perfectly mirroring the show's suspenseful atmosphere.
