Baek A Yeon charms with her breezy, folk-tinged take on pop music. She finished in the top three on the Korean singing competition K-Pop Star in 2011 and soon joined major label JYP. Since then, she's crafted skippy midtempo pop songs full of acoustic guitar and twinkling keyboards—tunes perfect for a walk in the afternoon sun. She also delivers big cheery numbers such as “Shouldn't Have…” featuring rapper Young K and can even brighten up a “Sad Song” with her dramatic voice. She has a gift for finding the good vibes in a song.
