I'll admit, I only got into Kimbra recently, through her vocals on Gotye's single "Somebody That I Used to Know."
Some of her other popular songs, like "Good Intent," "Cameo Lover," and "Settle Down" are good from a musical perspective, but I just couldn't get into them. They're bright pop songs, and I need something deep and resonant.
However, I love "Plain Gold Ring." Watch the live performance and you'll see why--Kimbra moves and breathes the music. It's an inspiring performance, and makes the song, from her album Vows, a total earworm.
