Reminds me of '90s R&B like Brandy or Monica. Lovely vocals, and I particularly enjoy the aggressive turns in the arrangement. I'd see this fitting more with mainstream R&B rather than indie's modern take on R&B -- dominated mostly by male vocalists with a penchant for electronic backdrops. Sounds more like a deep cut on the album too rather than a lead single.
I like this track but its lacking something. The beat and vocals are nice but they are missing a certain edge. I would emphasize the melodic elements - they get pushed to the background. A piano type sound would be nice. A tighter/punchier kick and snare are also needed. The snare should change in the chorus.
