Singer-songwriter Grace VanderWaal (Jan. 15), at just 15 years old, is already the most amazing cross between Taylor Swift and whispery, indie musician Cat Power, while still being completely unique ever since her beginnings on America's Got Talent with her ukulele. "I Don't Like You" is the anthem you didn't know you needed, and other songs like "So Much More Than This" are both catchy and lyrically meaningful.
